基于小波变换和全相位内插的Bayer模式图像压缩算法

Many consumer digital color cameras use a single light sensitive sensor and a color filter array (CFA) with each pixel element recording intensity information of one color component. The captured data is then interpolated into a full color image. Bayer patterned CFA and a few kinds of compression-first interpolation-later approaches were introduced. On the basis of previous studies, Bayer patterned color image compression algorithm based on 9/7 biorthogonal wavelet transform and all phase interpolation was proposed and realized. Experimental results show that the proposed algorithm is suitable for Bayer image compression.
