Analysis of CFA video encoding efficiency

Abstract

CFA (Color Filter Array) image and video compressions are discussed in this paper. Traditionally, the CFA image is demosaicked before compression. In a state-of-the-art method, the CFA is compressed before the demosaicking processed in RGB domain. In this paper, we proposed to compress the CFA video in YCbCr domain with the same amount of data as in CFA before compression. Compared with the state-of-the-art method, the proposed work improves the bitrate reduction by 37% with some CPSNR loss.
