Quality Control or QC is a process in which entities review the quality of all factors under production. Control involves inspection of products visually using stereo microscope and comparing results with the description of unacceptable products to uncover the defects and determination of allowance or rejection of product release.

This paper reviewed the method for testing of objects automatically by using the captured images of objects and applying various image processing techniques such as contrast enhancement, pre-processing, background subtraction and morphological operators. This method is more efficient, more accurate and requires less time.
