Abstract

Images in any digital camera is formed through interpolation. Interpolation involves estimating values of R, G and B components separately and then merging them altogether to form a complete color image. Before interpolation image rays are made to pass through Bayer Filter, which arranges them in an alternate pattern where 50% pixels are of green color and remaining blue and red pixels are of 25-25% respectively. Interpolaion involves estimation of the missing color components to reconstruct a full image. Few algorithm results in formation of artifacts(zippering effect) which degrade the image quality. This paper gives a concise study of few adopted algorithm along with their advantages and disadvantages.
