• 48 bits color & 16 bits grey image support added.
  • Color analysis can now be done on 48 bits color images for greater precision and accuracy (12 to 16 bits of color information per channel [Red, Green and Blue]).
  • Can now load, scan, edit, analyse and save tiff 48 bits color and 16 bits grey levels images.
• Canopy & Sky menu renamed Canopy.
• Analysis/Canopy & Sky Detection renamed Canopy Detection and is now more responsive with color images. Non "Expert" level now hides NDVI canopy detection.
• Image edition done in the Detected Canopy image can also be applied to the Original image.
• The Original image can now also be edited after the analysis. The Analysis is redone with pixels reclassification after edition. Note: If the Detected Canopy image is edited, pixels reclassification is not redone.
• Interactive hemispheres position and size are now automatically stored in the configuration file for later recreation on other images (previous versions required to do a menu command to store it).
• Long Tooltips (temporary text displayed in yellow box when the mouse cursor is held over a window item) are displayed on more than one line.
• WinSCANOPY and XLScanopy are now bilingual (French and English). The language choice is made in the Misc. menu or in the Welcome screen at start-up.
  
  

  Bug Fix

  Pro Version

  • Color /New Class won't do a reanalysis if the new class is cancelled.
  • Color /New Class will ask if user wants to reanalyse existing analyses (of current and/or all documents) or not if a class was added.

  All Versions

  • After edition of a color original image now asks to update the analysis or not (if one exists or if there are more than one document (main window)). Previous versions required to cancel the analysis after edition and redo it.

Release date: 10 March 2020

• WinSCANOPY is 3.75 (default settings) to 8.5 (Mask, Filters, Gap Size Dist.) times faster thanks to its Multi-Threaded support (which does tasks in parallel). The speed increase varies in function of the complexity of the analysis (the processings done) and the number of processors/core/threads in the computer. Faster speed gain can be obtained by using higher end computers than those used by Regent in Oct 2019 to make the speed tests.
• Masks are faster. User can choose slower masks that consume less memory when the latter is thight.
• WinSCANOPY has a better responsiveness, the analysis can be cancelled at much more places.
• Latitude and Longitude are saved with more decimals (5 instead of 2). Altitude with 2 decimals instead of 1.
• Arrow keys can no more be used to change the right mouse click slider position (to change the threshold on a part of the image). This has been done to keep keyboard focus to change ring or from orange to green and vice versa.
• Image Masks have been removed.
• NDVI measurements and features are now in the Pro version (instead of Pro NDVI).

Bug fixes:

• WinSCANOPY Pro NDVI
• Spectral Index Data Display in Command Area setting (on-off) was not set properly. It was set as the same as the Active Suntrack Data (if the latter was on Spectral Index Data was also on, if it was off Spectral Index Data was also off).

  • A Scale can be drawn in the Image area to show the relative size of the image content.
• The analysis progress bar and message is displayed in the center of WinSCANOPY 's main window (to avoid hiding the title bar).
  
  
• WinSCANOPY 64 bit: A new 64-bit version is now available (as an option at an extra cost). It can analyse larger images and is faster by 5 to 7% compared to the 32-bit version. The 64-bit version can load analysed images made with the 32-bit version but the reverse is not true. Images analysed by the 64-bit version can only be reanalysed/validated with current and future 64-bit versions, not with the 32-bit versions. Data files (containing measurements in .txt files) are identical for both versions however. The 64-bit version do not replace the 32-bit version which will still be updated in the future.
  

Bug fixes:

• WinSCANOPY's MainWindow not visible at startup in very rare situations (easy to overcome by using default settings at startup).

• Free style Masks are done much faster.
• It can read orientation (heading) data from Electronic compass or GPS which store them in tiff images files (like our latest 12 MP Point&Shoot).

• More built-in camera and lens models.
• User can create lens.cal file.
• The display of Color classes, Color groups or Original image images is now done in alternation by clicking the Color image selector in the Command Area (the displayed image is changed each time you click it).
• The mouse cursor color (in the Image Area) can be changed.
• Global threshold: You can choose between the method that was used in versions 2003 and less (for compatibility or for better results with some images) or the versions after it.
• Other minor display and bug fixes.
• Revised manual and new pdf manual.
• NDVI and Color index analyses removed.

• (Pro) New measurements have been added:
  • The NDVI (Normalized Difference Vegation Index) which is widely used in agriculture and forestry healthinest/stress assessment. It requires two images of a scene, one in the NIR (near-infrared) wavelengths and one in the Red. NDVI images and data can be created interactively or in batch (without operator supervision) from NIR and R images stored in a folder.
  • Color indexes can be computed on color images. The user can define its own index as a mix of an image RGB (Red, Green or Blue) channels or the ratio of two such mixes. One frequently used index, the Greenness also used in agriculture and forestry healthiness/stress assessment, is pre-defined. Color indexes images and data can be created interactively or in batch (without operator supervision).
• (Pro) Reflectance calibration can be done using multi-steps targets to get reflectance measurements data and image.
• (Pro) WinSCANOPY will automatically extract the direction GPS datum when it is present in tif or jpeg files. It can be used as the hemisphere orientation.
• (Pro) The Latitude and Longitude GPS data are now read correctly as degree, minutes and seconds (instead of decimal).
• (Pro) Automatic extraction of GPS data (Orientation, Latiutude, Longitude, Altitude) can be turned on or off.
• (Pro) Improvements to color calibration. White balance can be done with or without pixel size calibration.
• WinSCANOPY now displays in the Information area (above the image) the pixel value at the mouse cursor position in the image. The data written depends on the image displayed. It can be; the RGB, Grey levels or Color index/NDVI value.
• Images can be saved with their masks with or without analysis (before it was possible only after the analysis’ first phase was done).
• Miscellaneous modifications to allow for larger image analysis.
• Minor bugs fixed.

• Image loading and saving in tiff files is much faster
• It can load one more color tiff file format.
• It can load wider (larger) images in old tiff format.
• Original and pixels classification images display at low zoom magnifications (1/16, 1/32, Fit) is done much faster (±4X).
• Image masks display at low zoom magnifications (1/16, 1/32, Fit) is done much faster (±4X).
• The “Fit” zoom magnification will display larger images.
• Right Click Slider (interactive pixels classification adjustment) is faster and work with larger images.
• All functions of the program have been revised/modified to ensure they work with very large images produced by high-end very high resolution digital cameras (and scanners).

• Automatic pixels classification is more accurate over a larger range of situations (from low to dense canopy cover).
• You can choose among two light attenuation profiles when using the Solar and Zenith Thresholds. One is linear (as before), the other is like the SOC (Standard Overcast Sky) diffuse sky light distribution. You can also choose the amplitude of the attenuation.
• There are more flexible pixels classification interactive adjustments. Modifications can now be done on pre-defined circular shapes (in addition to the previously available free-style regions made with the lasso tool) that can be centered on the zenith (per sky ring) or the sky brightest position.
• The graphic above the image has three new data types; gap size distribution, clumping index and leaf projection coefficient in function of zenith.
• It is possible to analyse hemispheres that extend beyond the image boundary. Useful when the hemisphere radius is large (close to the image vertical size).
• The Masks/New/Parametric command is faster.
• During hemisphere creation, it is possible to display only its four edges simultaneously to ease the hemisphere centering in the region to analyse (for those who do not use our calibration).
• The north direction indicator can be rotated faster (during an hemisphere creation).
• Radiation received takes into account slope and aspect.
• You can choose the zenith view angle at which the Bonhomme and Chartier LAI method is calculated. 57.5 degrees is the default.
• The sky grid and suntracks can be displayed while the panoramic display mode is active. When you click it, the relevant information (zenith, orientation...) are displayed in the command area.
• The clumping factors have been replaced by their reciprocal called clumping indexes (clumping index = 1.0/clumping factor). This allow to compare them to the new ones calculated by the gap size distribution analyses.
• It is possible to save analysed images during batch analysis (all or a sub-sample of them for a random verification).
• There are more image magnifications (zoom factors) and a fit-to-screen option (adjusts the magnification so that the image fits entirely in the main window using the maximum area available).
• The command area is larger so it can display more information.
• Elevation angles have been replaced by zenith angle. Previous versions used both "elevation" and "zenith" in various commands or data, now it is standardized on zenith.
• Data/Data File Format has been renamed Data/Information & Global Data and has been simplified (information and data saving can be enabled/disabled by groups of items).
• Data and information in global data lines have been reordered so that those related are grouped together.
• In log average LAI methods, (Lang and Xiang 86) you have more choices regarding the processing of regions with a zero gap fraction (no sky pixels). You can choose between a default gap fraction value or a default number of pixels to be classified as gap (typically "1" but it can also be a fraction of a pixel).
• Choose the number of rings used in the LAI 2000 LAI method.

• Color channel change is now compatible with batch analysis.
• LAI will be calculated in more situations when masks are used (especially when complete rings are masked).

• Support for latest cameras*:
• A new type of mask, Image Mask has been added. An image mask is an image stored in a tiff or jpeg file which indicates areas of the image to be masked (not analysed). They can be produced by many types of programs (image editors, GIS, ESRI, ArcView (programs who compute view sheds based on digital elevation models,...) or within WinSCANOPY itself by drawing the mask with the edition tools.
• Pixels classification (into canopy and sky) can be modified or specified for regions of any shape, before or after completion of the analysis. This method is more interactive than the previous Pixel Classifier. Pixels that falls into the canopy group are drawn a different color over the original image as the threshold (pixel classification criteria) is modified by moving a slider bar.
• Image edition is more precise.
• The pixels classification image can be edited. Which means you can manually classify pixels directly by drawing in the classification image rather than the original image.
• Lens.cal or custom hemispheres can be moved during their creation. Useful with DSLR cameras which don't have a stable (repetitive) hemisphere position in the image. Regent Instruments has designed a device which render such position adjustment unnecessary by stabilizing the lens position on the camera. The cameras we sell come standard with it.
• Hemispheres position can be changed after they have been created.
  
• Flickering when resizing the main window has been removed.
• The lens.cal camera-lens parameters can be copied to a custom (defined by numerical parameters) or interactive (defined by clicking and dragging in the image) camera-lens pair. Practical when you simply want to change some parameters without reentering all of them.
  
• A lens calibration (made of a polynomial of order up to 9) can be created by entering a list of zenith angles and their corresponding projected position in the image (determined experimentally).
  
• Lens calibration coefficients can be saved and retrieved from files (for user defined customs lenses).
  
• Minor modifications
  
  • jpeg is now the default image type when opening an image (instead of tiff)
    
  • Latitude and longitude can be specified in degree-minutes-seconds (in addition to decimal) format.
    
  • It can scroll larger images with the scroll bar thumbs
    
  • A crash situation removed when editing while pressing the backspace key
    
  • Camera, Lens and Hemisphere has been renamed Camera and Lens.
    
  • Duplicate Last Hemisphere has been moved from the Analysis menu to the Hemisphere menu and renamed Duplicate Last.
    
  • The appearance of some windows (dialogs to enter settings) have been redesigned.
    
  • Camera has been merged with Scanner in Image/Origin.
    

*NOTE: Not all the above cameras-lens specifications are included free with the program. Contact our sales dept. for details.

Release date: March 1st, 2004.

• Leaf clumping compensation has been added. The four previously available LAI methods are calculated with linear gap fraction averaging (as before) and with logarithm averaging. With linear averaging, gap fractions are calculated for each elevation annulus then the logarithm is calculated and fed into the standard equations. With logarithm averaging, gap fractions are calculated for each sky region (segment of annulus), then the logarithm is calculated per region and the average is then calculated per annulus and fed into the standard equations. According to the litterature, the log-average method gives better LAI estimates for clumped canopy.
• WinSCANOPY's calculates a clumping factor.
• Radiation analyses are 29% faster.
• Ground slope is now taken into account in two LAI estimation methods and in direct radiation calculations. Regions of the image that faces the ground instead of the sky or canopy are identified. Direct radiations blocked out by the ground are also visible in the suntracks over the image.
• You can set the elevation (zenith) angles at which each sky annulus begins and ends (they do not need to be equal).
• Images can be analysed with different sky grids in a single pass. You can define up to 10 different sky grids and analyse each image with all of them with a single mouse click.
• There are more camera default settings to accomodate new models.
• bmp files opening and analysis possibility has been put back.
• It is now possible to analyse images of different aspect ratio then the one that was used for calibration.
• The selection of view caps orientation is easier thanks to a more interactive interface.
• The Threshold image has been renamed the Pixels classification image.
• Our LAI2000 generalised and Ellipsoid LAI estimation methods now use the same elevation rings as the diffuse sky.
• Openess per elevation annulus has been added.
• WinSCANOPY counts and displays the number of sky regions with a zero gap fraction value. These regions are also identified in the image by a red cross in their centre.
• All LAI methods are active by default.
• A red rectangle is drawn around interpolated data in the image when Mask LED presence at north position is active in Analysis/Masks (this helps verify if the specified LED region is good).
• There are still more tooltips that give information about the main window areas (graphic area, command area and information area components) when the mouse cursor are over them. Tooltips have been added also to the Hemisphere identification window.
• Display groups rather than classes has been moved to the Color menu (like our other programs).
• You have more control on what is displayed in the command area. There are more data to display also.
• Structure/ Gap Fr. Openness, Sky Grid has been renamed Structure/Sky Grid.
• WinSCANOPY will remember the last image format loaded (bmp, tif, jpg).
• The NDVI menu is gone (it was inactive in previous versions).
• The manual has been improved. There are more theory and precisions about the calculations.

Known bug (solved in version 2003a)

• When FOV Used is different than FOV Max, WinSCANOPY will crash if the Sun size method is set to Real Size or Real Size Plus Penumbra. There was no crash is the method was 1 pixel.

• This version solved a problem with batch analysis (the analysis sometimes stopped after the first image).
• It can analyze jpeg images in batch mode.
• It can analyze images of any resolution in batch.
• A problem with the menus in French has been solved. 

• The file version warning has been removed. It was displayed when opening a file more recent than 2006 such as those produced by WinSCANOPY version 2009a or 2010a.
• A bug preventing to analyse the first data file (when a warning was displayed at opening) has been removed. The file had to be loaded a second time before data was separated into different sheet and graphics could be done.
• It can now analyse data with a Photo Identification number larger than 32767 (previous versions generated a Run Time Error 6).
• It can now analyse files with data lines longer than 256 columns. Excel 2007 or more is required.
• Revised manual.

• A new graphic has been added: total radiation per day.
• Known bugs have been fixed.
