Study of algorithm for high compression ratio and low loss image coding
Luo Dai-sheng · Journal of Chengdu University of Information Technology · 2008
Referring to some existing image compression methods a concrete method of twice compression is presented.First,the discrete cosine transformation,linear transformation,linear quantization and Huffman encoding are used to implement the loss compression.Then the run-length encoding is used to implement the lossless compression.The algorithm principle is introduced and the processes of the rock images through the programming are studied.The experiment results show that this algorithm attains the aim.
