Lossless Image Compression by Block Matching on Practical Massively Parallel Architectures

Abstract:
Work-optimal O(log M log n) time implementations of lossless image compression by block matching are shown on the PRAM EREW, where n is the size of the image and M is the maximum size of the match, which can be implemented on practical architectures such as meshes of trees, pyramids and multigrids. The work-optimal implementations on pyramids and multigrids are possible under some realistic assumptions. Decompression on these architectures is also possible with the same parallel computational complexity.
