ABSTRACT

Demosaicing is a process of obtaining a full color image by interpolating the missing colors of an image captured from a digital still and video cameras that use a single-sensor array. This paper provides an effective iterative demosaicing algorithm applying a weighted-edge interpolation to handle green pixels followed by a series of color difference interpolation to update red, blue, and green pixels. Then border of the image is enhanced using some adaptive techniques. Experimental results show that the proposed method performs much better than other latest demosaicing techniques in terms of image quality. In comparison to the other algorithms, this algorithm proposed here results in increased PSNR value.
