This paper presents a cost-effective hybrid demosaicing algorithm for Bayer color filter array images. Unlike many iterative methods that require interpolating each color plane many times, the proposed algorithm requires only three times. Two edge-sensitive algorithms, one modified and the other new, are proposed to interpolate green pixels along the edge orientation in the color-difference space. Experimental results show that the proposed algorithm achieves more satisfying image quality than previous demosaicing techniques in terms of subjective and objective measurements, especially at peak signal-to-noise ratio.
