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.

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?
