主要包括图像的中值、均值去噪、非局部均值、分块局部去噪算法；还有均方误差和峰值信噪比评价、以及matlab基础学习资料如边缘检测、小波变化、灰度值转换等-Including image median, mean denoising, non-local means, block local denoising algorithm also mean square error and peak signal to noise ratio evaluation, and matlab based

代码中有传统的图像增强算法：对数增强，均值滤波等；也有图像去噪代码；以及对PCNN算法进行改进的图像增强算法。(There are traditional image enhancement algorithms in the code: logarithmic enhancement, mean filtering, etc.; there are also image denoising code; and the PCNN algorithm is improved image enhan
