把ICA和NLM结合一起的去噪算法程序。先对噪声图像进行ICA处理，然后用NLM滤波对处理结果进行二次处理。效果比直接用NLM对噪声图片滤波要好。-ICA and NLM combined with the denoising algorithm program. Firstly, the noise image is processed by ICA, and then the results are processed by two times with NLM filter. Effect is better than the direct use of NLM to filter the noise image.
