Detailed Description

The ClassifiedHSImage class is the interface for interacting with classified hyperspectral images.

The ClassifiedHSImage class contains an HSImage as its internal logistic engine and adds functionality aimed at classification and detection research. The class allows for retreival of pixels by class label and the setting of image classes by pixel or by setting an OpenCV cv::Mat object with the pixels colored according to the class label color.

Does not current support internal saving of files. Under construction.
