Edge-oriented constant-hue scheme for color filter array demosaicking

In order to reduce the cost and complexity of the system, most digital still cameras use color filter array to sample the scenery. The sample image information needs proper interpolation/demosaicking to present complete image. This paper proposed a novel method for color image interpolation to promote the process result and do not cost large hardware and process time. In the experimental result, our algorithm only added some exquisite compare function and provided fine image quality. Because of the simple operation, it is easy and fast in hardware implementation.
