二进制冗余无记忆信源的线性复杂度有损压缩器

Linear Complexity Lossy Compressor for Binary Redundant Memoryless Sources

Kazushi Mimura

摘要:

提出了一种二进制冗余无记忆信源的有损压缩算法。所提出的方案是基于稀疏图码。通过引入一个非线性函数,冗余无记忆序列可以被压缩。我们提出了一个线性复杂度压缩机的基础上扩展的信念传播,其中的惯性项是启发式的介绍,并表明它具有接近最佳的性能为中等块长度。

英文摘要:

A lossy compression algorithm for binary redundant memoryless sources is presented. The proposed scheme is based on sparse graph codes. By introducing a nonlinear function, redundant memoryless sequences can be compressed. We propose a linear complexity compressor based on the extended belief propagation, into which an inertia term is heuristically introduced, and show that it has near-optimal performance for moderate block lengths.
