摘要/Abstract:
This paper presents a new method for near-lossless image compression for digital colorful image sensors with Bayer Color Filter Arrays (CFAs). In this method, the captured CFA raw data is first smoothed by low-pass filters followed by down-sampling and then compressed directly before full color interpolation which introduces redundancy. Assuring high image quality, the method can provide higher compression ratio and lower complexity than conventional image compression methods and other existing similar methods. The Composite Peak Signal to Noise Ratio (CPSNR) of decompressed image is larger than 51dB.
