ICA（主分量分析）算法和程序，采用热核构造权重，实现了图像的加水印，去噪，加噪声等功能。- ICA (Principal Component Analysis) algorithm and procedures, Thermonuclear using weighting factors Realize image watermarking, de-noising, plus noise and other functions.

ICA算法去除基本噪声 脉冲噪声 随机噪声 工频噪声(CA algorithm removes basic noise, impulsive noise, random noise, power frequency noise)

基于FastICA的改良算法 去噪效果明显 有自适应性(The improved algorithm based on FastICA has obvious denoising effect and is adaptive)
