Bayer patterned image compression based on wavelet transform and all phase interpolation

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 more suitable for Bayer image compression.
