Cascade Trainer: Specify Ground Truth, Train a Detector
Updated 14 May 2015
Cascade Trainer app:
Interactive app for managing the selection and positioning of rectangular ROIs in a list of images, for specifying ground truth for training algorithms, and for creating new cascade classifiers.
* Add/remove/rotate/sort images
* Add/remove/reposition/ delete/copy/paste ROIs
* NEW: Paste ROIs from a specified image through a range of images
* Generate/export structure of image names and ROI positions
* Save/restore sessions
* Keyboard shortcuts designed to facilitate the process
If you plan on training a detector, or have other uses for multiple-ROI selection and management, this tool is for you!
Note that the zip file includes an mlappinstall file. You can use this GUI in the standard fashion, or double-click the mlappinstall file to install CascadeTrainGUI as an App on your App Toolbar.
Comments, suggestions welcome!

This is the fixed version that was supposed to go live on 5/4/2015, but that apparently didn't get updated correctly. Sorry for the inconvenience!
Fixes a bug that triggered the "negativesFolderNotFound" error under certain training conditions.
Added new capability for inserting full-frame ROIs through a specified range of images, and made that and "pasteROIsThrough" fast! Fixed a couple bugs, and removed a dependency that rendered this Windows-only.
Added new PasteROIsThrough... function, fixed some bugs, and verified R14b readiness.
Includes interface to train a detector, and to apply a trained detector to a series of images!
