Create image from an Image

Hi, I got this image using segmentation with CNN. Is there a way I can obtain multiple images "cutting" everytime image is black? I need the blue part but separately. Thanks very much

Sum the image horizontally. Untested code:

verticalProfile = sum(rgbImage(:,:,3), 2); % Collapse across columns.
% Then find out where it's not black
nonBlackRows = verticalProfile ~= 0;
% Now find the starting and stopping points
props = regionprops(nonBlackRows, 'PixelIdxList');
% Now crop
for k = 1 : length(props)
    row1 = props(k).PixelIdxList(1);
    row2 = props(k).PixelIdxList(end);
    imageList{k} = rgbImage(row1:row2, :, :);
end

Each image is in a cell of the cell array. They might all have different sizes.
