In this paper, the authors have researched and realized a kind of scheme about image lossless coding based on integer DCT and its main ideas are as the following: firstly, design reversible integer DCT based on integer FFT; and then dealt with the DCT data by SPIHT; finally, encoded the data by Arithmetic Coding. In this paper, the authors deduct and prove its theory based on the works of other researchers and the basic knowledge of digital image processing. Then the its mathematical model is established and suitable algorithms are achieved. The calculation shows that this lossless coding system based on integer DCT is of higher compression performance.
