Hello everyone,
I need image output from viola jones algorithm. I have used Viola jones on gray image and result has square box around face regions in image. I need these detected face images for further processing.
how i should take out those detected faces and save it as image?
Thank you in advance.

When you step() the viola jones detector, you get an array of bounding boxes. You can loop through each row of the bounding box, passing the row to imcrop.
bbox = step(my_viola_detector_object, IMG);
nbox = size(bbox,1);
pieces = cell(nbox,1);
for K = 1 : nbox
pieces{K} = imcrop(IMG, bbox(K,:));
end
