Abstract:

The digital still camera acquires the color data using single sensor in which only one color element can be recorded at each pixel. Efficient demosaicking algorithm is necessary to rebuild the other two missing color elements in each pixel. This paper proposed a gradient based edge sensing algorithm for color filter array interpolation to enhance the edge information and avoid zipper effect. Our method first extracts the gradient in different directions and exploits the gradient edge detection to restore the color channel in detail. Experiment results show that our algorithm performs superiorly in PSNR and visual image quality compared with other algorithms.
