Abstract: Typical consumer digital camera sense only one out of three components per image pixel because of increase in size and cost of sensor used in camera. An effective demosaicing is presented to restore the missing pixels of image captured from single sensor cameras. To eliminate most of color artifacts in edge region, Edge based demosaicing algorithm is to interpolate missing green sample followed by interpolate red and blue samples. Many demosaicing algorithms find edges in horizontal and vertical directions, which are not suitable for other directions. Before using the algorithm Gaussian filter is used for edge enhancement and smoothing of image. This proposed algorithm will be compared with other existing algorithms using PSNR measure.
