Don't count pixels: count regions. When you regionprops() to find the centroid for tracking purposes, then the number of regions found will be the same as the length() of the structure that is output from regionprops.

Sir, but i want to say that i want to make any object as a closed one and to convert in a any shape such as a square...and then counting this will be easy and perfect

You can easily count using bwlabel.

[~ , numberOfObjects] = bwlabel(BinaryImage)
