针对传统的ICA算法存在的计算复杂度过高,训练和识别消耗时间过多的问题,通过对一般的用于人脸识别的小波变换(WT)方法加以改进,实现了一种基于WT的ICA算法-Spend too many time-consuming problem of high training and recognition complex calculations exist for the traditional ICA algorithm to be improved by the method generally used for face recognition wavelet transform (WT), to achieve the ICA based WT algorithm
