A Lossless Compression Algorithm Based on High-resolution CCD Images
Shihong Yang · Bandaoti guangdian · 2008
A lossless image compression algorithm is proposed based on the images obtained from the first domestic superhigh resolution CCD camera.Based on the embedded wavelet zero-tree coding algorithm,by adopting run length coding for the bit-plane output of the embedded zero-tree algorithm,the compression ratio and the coding efficiency are improved greatly.The experimental result shows that BPP of this method is reduced more significantly than that of classical embedded wavelet zero-tree algorithm.
