Hello, please help me to improve training my classifier. What I want is just function that after step metod of vision.CascadeObjectDetector on test image, will crop from that image (that I just tested to detect any objects) all detected bounding boxes and write each detected box as a separate image to separate file and save eache of them in one directory on disk (for example in c:\test).
If I can do it then I believe I can use many of these new images as negative images to train my classifier to be more accurate. Could someone help me please with the function I described?
P.S. Below just the information from Help about this step method: BBOX = step(DETECTOR,I) returns BBOX, an M-by-4 matrix defining M bounding boxes containing the detected objects. This method performs multi-scale object detection on the input image, I.
Each row of the output matrix, BBOX, contains a four-element vector, [x y width height], that specifies in pixels, the upper left corner and size of a bounding box.

See how I crop out blobs according to their bounding box in my Image Segmentation Tutorial: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862
