Adaptive Constant Hue Algorithm Design of Color Filter Array

In this paper, we proposed an "adaptive constant hue algorithm design of color filter array." The method is an extended application of the edge algorithm in the spatial domain algorithm. The main method is to do finer angle calculation on the basis of edge judgment. When the angle judgment is finer, it will be closer to the original image plane. The algorithm we propose is to use multiple angles to perform high-order interpolation adjustments to obtain better image quality. We use standard test images to simulate, and use subjective judgment, PSNR value and computational complexity to compare the effect of the algorithm. The experimental results prove that our proposed method can improve the reconstructed image quality and the color accuracy with a lower computational complexity.
