Demosaicing Algorithm Based on Pixel Grouping

This paper describes a new color filter array demosaicing algorithm that makes use of some properties of images’ pixel grouping. We found this algorithm can reduce some of the common artifacts introduced by the demosaicing process according to the result of experiment. Preliminary studies show that the performance of the algorithm is generally comparable to both Variable Interpolation by Gradients and Linear interpolation. The new algorithm overcomes some deficiencies of above two algorithms in specific cases.
