I used bwlabel for detecting connected components but i got error output i.e 3 objects are detected instead of 8. I am attaching input image. Expecting your suggestion.

bwlabel assumes that the white pixels are where the data is and that the black pixels are holes. When you have black text on a white background you need to invert the image.

Or you could sum the image vertically to find the gaps between the symbols.
