Stats = regionprops(BW , 'BoundingBox'); % BW is your preprocessed binary image.
for ii = 1:length(Stats)
croppedImage = imcrop(origionalImage , Stats(ii).BoundingBox);
imageName = strcat('croppedCharactor' , num2str(ii));
imwrite(croppedImage , imageName , format) % see docmentation for allowed formats.
end

You can see that in a larger context of an Image Segmentation Tutorial in my File Exchange http://www.mathworks.com/matlabcentral/fileexchange/25157-image-segmentation-tutorial-blobsdemo. It crops out the sub images it found.
