Abstract

Digital cameras usually uses single sensor covered with Color Filter Array (CFA) to capture the image which reduces the cost and size of the camera. The CFA samples only single color value at each pixel location. To render the full color image, the missing two color components at each pixel is to be estimated. The process of estimating the missing component is called as demosaicing or color filter array interpolation. The proposed research uses the edge oriented filter named as edge strength filter which uses the edge information accurately. The missing components are interpolated by making the hard decision with the edge strength map. The reconstructed image still remains in color artifacts to reduce this problem, the refinement process is implemented. The low pass filter is used in refinement process to separate the low and high frequency components further interpolation technique is applied. The proposed technique produces the high quality image with less computational complexity.
