Without definition of what you mean, the "center" of an irregular shape is a meaningless concept.

Of course, since an image is generally a rectangular collection of pixels, the center of the image is trivial to find. And you did ask for the center of an image.

i want find center of foot ..what mean the center of the image is trivial to find. And you did ask for the center of an image.you mean this foot not content center

[John D'Errico]

That is my point. The center of a rectangular image is trivial, because you need merely count pixels.

My other point was a more significant one, that you need to define what it means to find the center of a foot, or ANY irregular object. There are many ways one might define "center". What that word means to you is probably not what it means to me.

Threshold it. Throw out small blobs with bwareaopen() or other methods. Then call regionprops() and ask for centroid. See attached m-file.
