analyse the coherence of two signals.

We propose a regional contrast based saliency extraction algorithm, which simultaneously eval- uates global contrast dierences and spatial coherence. The proposed algorithm is simple, ecient, and yields full resolution saliency maps.

相对码及其反码分别和载波相乘再相加，即得到调制信号 解调 解调系统中，极性比较法和差分相干法有很多部分相同，可以用相同设计 -Relative code and its inverse code respectively and carrier multiplication and then add, get modulation signal demodulation In the demodulation system, the polarity comparison m
