The code i used is
Ch = bw(boundrow(1):boundrow(end),boundcol(1):boundcol(end));

Best Answer

Presumably you used regionprops()
props = regionprops(binaryImage, 'BoundingBox');
% Plot all the bounding boxes.
hold on;
for k = 1 : length(props)
    rectangle('Position', props(k).BoundingBox, 'EdgeColor', 'y');
end
