| Abstract: | Data are acquired by the CCD or CMOS image sensor through the Bayer Color Filter Array.Based on the research on the characteristics of the Bayer image,some near-lossless compression methods and issues of Bayer pattern image are discussed.The performance of these compression methods is evaluated by CPSNR method.Finally,a pre-process method is simulated and tested by hardware of FPGA,which turns out to be effective in practice. |
