I'd first try imtophat() or imbothat() to emphasize the spots. Then it really depends on what area(s) of the image you want to crop, like each letter, each paragraph, the whole group of paragraphs or what???.

I'd take projections vertically and horizontally to try to find natural breaks in blob locations.
verticalProfile = sum(binaryImage, 2);
horizontalProfile = sum(binaryImage, 1);
