A wavelet-based intra-prediction lossless image compression scheme

We propose a wavelet-based intra-prediction image coding scheme that is very efficient for lossless compression. This scheme takes advantage of JPEG-2000's wavelet decomposition and H.264's intra-prediction capability to compress still images. The compression performance is analyzed, and the results demonstrate that our method outperforms H.264 intra-mode coding by about 7% and JPEG-2000 by around 15% for the lossless case.
