  • confusion matrix view showing detailed error information
    • interactive performance optimization in a confusion matrix (slider in right-click context menu or a mouse wheel on confmat entries)
    • confusion matrix shows normalized errors and precisions, absolute sample counts available as well
    • quickly switch to confmat with 'c' key and to spectral plot with 's' key
    • define performance constraints via double click on a confusion matrix field (create/remove constrain)
    • constraints may be adjusted live by Ctrl+mouse wheel
    • constraints may be enabled/disabled to understand available performance options
    • move between available solutions fulfilling all constraints with [ and ] shortcuts
  • preview image from user-adjustable R,G and B bands when spectral cube is loaded
    • this view improves labeling experience for many material types that look similar in a single band but their differences may be highlighted in R,G,B view
  • undo/redo for label painting speeds up labeling
  • image crop providing significant memory use reduction and processing speedups
    • when a project with a cropped image is loaded, the original cube is loaded and cropped
    • original cube may be loaded as a new image and multiple crops from the same cube are supported
  • including perClass Runtime DLL and example of spectral cube processing in C
    • support for both single precision and double precision pipelines (with a new perClass 5.4 Runtime)
    • significant speedup of exported classifiers
    • legacy export option supporting older deployed runtimes <= 5.2
  • a preview rotation command allows one to fix the rotation between preview and spectral cube (e.g. on Specim IQ projects)
  • adding an option to exclude a class from training (right-click in class list or press 'x')
    • this allows one to quickly check the impact of specific classes on the overall solution
  • option to purchase a license online and directly turn the demo into a commercial product
  • dialog to request Skype/Teamviewer session on start up
  • fix for a wrong class index after removing a class
  • fix for clear labels of an image

1.0 13-jul-2018

  • fix for a dock shift bug (when resizing a docked window and clicking on the image, the docked pannel resized back)
  • adding band line dragging by mouse
  • adding max valid line which is automatically set on image load
  • when user is on preview and tries painting, a dialog is shown to load the entire cube (allows quick image changing without load)

  • first public release
