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.

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!
1.7.0.0

Fixes a bug that triggered the "negativesFolderNotFound" error under certain training conditions.
1.6.0.0

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.
1.5.0.0

Added new PasteROIsThrough... function, fixed some bugs, and verified R14b readiness.
PLEASE NOTE: This app is a replacement for the previously-named CascadeTrainGUI.
1.3.0.0

Includes interface to train a detector, and to apply a trained detector to a series of images!
1.2.0.0

Includes interface to train the detector, and to apply a trained detector to a set of images!
1.1.0.0
