In the people routine life or day-to-day experiences, many objects that perceive are in circular form like coins, rings, etc. The detection of their presence in an image reliably and efficiently is an important task in image processing. The Hough transform techniques for detection of shapes require a huge memory space for data processing, hence needs a lot of time in computing the location of the data space, writing to and searching through the memory space. In this paper, it is propose an efficient scheme for circle detection in grayscale digital images.
