unsigned char * | img |
point to the grayscale 8-bit image data |
a tracking_window
is most commonly used with functions that are interested in the position information of the object (blob) and the ROI. These functions are typically image processing or tracking routines used to update future positions of the ROI. If extending the vision system to include more image processing or tracking routines expect to use this structure often.
