Comparation of the original signal and the filtered signal

数字水印DCT算法设计，可以进行优化，希望大家一起将程序优化(DCT digital watermarking algorithm designe，it can be optimized and I hope that everyone can work together to optimized it.)

This letter addresses the problem of fetal electrocardiogram (FECG) extraction. A class of source extraction algorithms is proposed, which uses a combination of two di® erent approaches: Barros s source extraction approach and HyvÄ arinen s ˉxed- point approach.

经典粒子群算法的matlab实现。用多维函数进行测试。并给出算法寻优迭代的效果图(Classical PSO algorithm matlab. Tested with multi-dimensional functions. And gives an iterative optimization algorithm renderings)

This code takes speech as input, removes silence region based on zero crossing rate and energy.output of the code is only voiced region of the input speech signal.the input is of the .wav format.
