Release date: 10 March 2010

• One more method for objects color classification (Pro).
• Exclusion regions are now available in the Reg version.
• Regions of Analysis (selections) are now available in the Reg version.
• Rejected objects are no more visible in the Pixels classification image and their area is now included in the background area (instead of invalid objects which is now gone).
• Minor changes to some command’s interface.
• Minor bugs fix.

Release date: October 2008

• This is the first version designed for and tested under Windows Vista (but it also works under XP). It has been produced by a different compiler (the latest available) and thus has inherited some enhancements of modern tools built-in (increased capacity or limits of some functions related to maximum image size).
• Analysis is updated when the calibration method or its parameters are changed (while an analysis is displayed on screen).
• Filters settings are saved with data in data files.
• Enhanced scanner calibration files. Allow WinSEEDLE to support new scanners (with their positioning system with regard to our simple scanning interface) without modifications to it (no need to release a new version to support a new scanner).

Modifications to the interface

• The mouse wheel can also be used to scroll the image horizontally (it was working before only in the vertical direction). Press ctrl and roll the mouse wheel to scroll horizontally. Press shift to scroll faster in both directions.

Modifications to the Command Area

• Its width can be changed interactively.
• You can right click the mouse in the Command area to set the information displayed there.
• The graphic above the image display status (set with the ShowHide graphic button) is saved and restored at start up.
• Will zoom closer to the mouse cursor location if it is in image area when pressing the “-” or “+” keys.
• The information area above the image will display more accurate information about the active calibration (scanner.cal, file, or none) when it is changed or canceled.
• Misc. minor changes to the window interface of a few menu commands.

Release date: January 2006

Calibration with Regent's targets (for images from cameras)

• It is now simpler and faster to calibrate and analyse an image with Seedles and a calibration target in the same image. WinSEEDLE will make the calibration on the displayed image (rather than loading another image) and it will automatically create an exclusion region around the calibration target. The region remains if the analysis is canceled but can be manually destroyed with Exclusions/Delete Last Exclusion Region.

Other modifications

• Exclusion regions content has no more influence on the automatic threshold selection.
• Objects' boundaries are drawn over the image when the perimeter measurement is activated.
• The analysis can be interrupted at more places (while the progress bar is displayed).
• Regent's target calibration method is selected by default when the Object of known dimensions calibration method is active (in Calibration/Method).
• Calibration can be canceled from more situations.
• Display/Information Content has been redesigned.
• There are more image zoom magnifications and a fit to screen option.
• When creating a circular analysed or exclusion region, you must move it or resize it otherwise the whole image is selected (similar to when the rectangular and lasso tools regions are made). Also valid for right mouse click threshold adjustment (slider).
• There are now 14 display information colors that can be changed instead of 12
• You can specify the RGB value of display information colors in numbers from 0 to 255 (in addition to moving the scrollbars).
• White balance calibration is now possible for color analysis.

Pre-Release date: 01 November 2004.
Final Release date: 01 January 2005.

Features of the Pro version

• You can analyse whole images or sub-regions of any shape. Circular and rectangular shapes are predefined or you can outline irregular shape regions to analyse with a lasso tool.
• Analysed regions can be resized at any time (the analysis is automatically updated).
• An analysis done with a sub-region (of any shape) can be recreated after (useful to analyse the same region in more than one image).
• Regions of the image can be excluded from the analysis. You can create practically an unlimited number of such exclusion regions and of any shape. Excluded regions content have no effect on the analysis (It's as if these regions didn't exist in the image).
• Batch analysis can be done on the whole image or a sub-region of it (of any shape).
• The histogram above the image can display area per color classes or groups.
• You can display a single color channel (Red, Green or Blue) of an RGB color image and analyse only that channel. You can also analyse the image in color as before or in true grey levels (calculated from the color components).
• Information about the dominant color class (area, hue, saturation intensity, and class name) is saved with the data.
• Color analysis global area data are available separately for the image or for the total areas inside valid objects of the analysis.
• New functions have been added to remove background light variations for images that come from cameras.
• Flickering when resizing the main window has been removed.
• The custom selected color for image edition can be modified by clicking its rectangle in the command area.
• WinSEEDLE will ask to save color classes before quitting if they have been created or modified but not saved during the working session.
• A warning asking you to confirm your intention is displayed when deleting all paths or all exclusion regions. The display of this warning can be turned off.

Features of the Reg and Pro versions

• Pixels classification (into seedles and background) can be modified or specified interactively for regions of any shape or the whole image, before or after the analysis. The process is very interactive and easy (more than the previous Pixel Classifier). Pixels that falls into the seedle group are drawn a different color over the original image as the pixel classification criteria is modified by moving a slider bar.
• The pixels classification image can be edited (like it was possible for the original image before) to manually classify pixels into seedles and background. The analysis is automatically updated when the edition is complete.
• The seedles frequency distribution histogram above image has been redesigned and improved. The classes boundaries can be set more easily and more than 12 different data types can be displayed and save to data files.
• Calibration of images from a camera can be done with a single mouse click when Regent's new calibration targets are included in the image.
• More options are available as to how and when calibration of images from a camera are done (manually or automatically after load). Targets used for calibration can be in the same image as the object to analyse or in separate image(s).
• You can choose to reject or not seedles truncated by image boundary.
• The analysed image has more color encoded information (the color used to indicate if an object is analysed, a debris, cut by image boundary, rejected manually...).
• Form coefficient measurement has been added.
• Global area data are more specific about rejected objects (area is available for background, valid objects and rejected objects).
• The area of the analysed image (or region for the Pro version) is saved with the data and displayed on screen.
• Image edition is more precise and a few minor annoyances have been removed (white brush, small brush, image zoom...).
• New and improved manual.
• Paths related commands
  • The last deleted path can be recreated.
  • More paths can be created.
  • Interactive menu renamed Path (and the word Path removed from its items).

Eligibility: Free if your free update period has not ended.

Pro version

• Interactive manual length measurements have been added.

All versions

• Data saving is now easier. It is done automatically at the end of the analysis (and updated automatically if you make changes to the analysis).
• More information is saved in data files. The analysis settings, image file name and resolution are now stored.
• Seedles invalidated (rejected) by the operator are shown in a darker red and can be revalidated.
• Reason for a seedle's rejection from the analysis is now available by clicking the seedle.
• Text size of the information displayed over the image and in the command area is now user selectable.
• The text of the graphic above the image is larger.
• Seedle numbers are continuous.
• Jpeg and Windows bmp files can be analyzed.
• Names of some measurements name have been clarified (Ex: projected area instead of area).
• Support for new scanners (STD1600+ and LA1600) has been added.
• Seedle perimeter measurement has been added.
• All seedle cross-section models are active at all times (you do not have to select one, they are all calculated).
• Two new cross-section models for volume and surface area calculation have been added. One of these methods allows measurement of needles with irregular cross-sectional shape (it can work with any shape).
• The rectangle cross-section model now uses the Height to Width ratio. The previous versions' model was square rather than rectangular.
• When analysis parameters are changed, a warning informs the operator if the changes are effective only after the current analysis.
• Save Image After Analysis has been renamed Save Image After Acquisition.
• Instructions manuals have been rewritten and improved. There are more illustrations.
• The computer CPU is no longer utilized at 100% while SEEDLE is idle.
• Modification to the calculations that influence the analysis results: Object widths are now one pixel larger. There was one pixel missing on width measurement in previous versions. This led to underestimation of the surface area and volume (but other measurements like projected area were not affected). One pixel is typically 1/400 of an inch or .063 mm, as most people scan needles at around 400 dpi.
• All surface area and volume calculations have been revalidated (no modifications other than those described above were required).
• It can analyze images with a greater number of objects. Earlier versions might crash when the number of objects is too high (several thousand). The exact number depends on the object shape complexity.
