We are trying to detect black color object through overhead camera and then we are taking black color object as a obstacle so we want to increase the region of the black color object ?

Mukul, your question is not clear to me. What do you mean by black color object? What is that "region of a color object" that you want to increase? Please give us more information about what you want to do and what your actual question is - otherwise it is impossible to answer it.

You can increase the size of the black object by calling imerode() which is like a moving local minimum operator. Insert your image if you want more advice.
