Demosaicing schemes consider a frequency analysis, the basic principle is to use a frequency illustration of the bayer CFA (color filter array) image. For red & green rows and columns within the input mosaick image as in the directional estimates for the absent red and green pixel values are calculated. For blue & green rows and columns within the input mosaick image, the directional estimates for the missing blue and green pixel values are calculated. The results observed in the study are associated with the quality of images, their color plane and structural similarity index. Simulation shows the performance of the proposed algorithm gives better quality than other demosaicking algorithms. The PSNR was used as a measure to quantify the performance of the demosaicking methods. Graphs are evaluated for the comparison of performance of various algorithms with proposed system. All the system is design by the MATLAB software.
