Can you show us what you mean by "object in an image". Please use example code such as:
I = ... your image
obj = ... your object

you have to convert your image first in binary (B/W) image then do pixel counting by finding maximum pixel value in row and same in column.

Not sure what you mean by it's separating points, not objects. It definitely gets the coins as objects and does not get individual points (pixels).
I'll give the answer in your own question, like I asked. But I don't see that you've posted it yet. Not sure why you're choosing not to.
Please, if you do like I asked, I would answer.

Let's say your object looks like an irregular shape - some amorphous blob. What do you define the width and length to be? Can you show us an image of what your blobs look like?
