摘要：
The Mojette transform is a discrete, exact and redundant Radon transform. The application of the Mojette transform for lossless image compression is based on image projection similarity using different directions, with intra-projection coding, inter-projection coding and differential coding schemes being applied. For the latter case, we propose mean coding of projections to improve the Mojette transform with different projections, and we calculate the difference between the projections and the mean. Experimental results obtained are shown to be better compared to inter-projection coding, and comparable with CALIC.
