图像处理的偏微分方程方法，包括曲线演化，图像分割，图像滤波，图像复原等的matlab源代码。(Partial differential equations of image processing methods, including curve evolution, image segmentation, image filtering, image restoration, etc. matlab source code.)

暗原色先验的视频去雾算法 matlab实现(the code of defog using dark-chanel prior algorithm)

对图像进行处理，包括加遮挡，旋转，仿射变换，形状调整等等。(Image processing, including plus occlusion, rotation, affine transformation, the shape of the adjustment.)

可以实现图像的重采样，通过设置参数来减小或增大图像尺寸(Resampling of the image can be achieved by setting parameters to decrease or increase the image size)

说明：  自己用python复现的NL-mean去噪，备注比较详细，便于理解原理； 之后会尝试复现更多图像领域的经典论文(The NL-mean reproduced by Python is used to denoise the noise. The notes are detailed and easy to understand the principle. We will try to reproduce more classical papers in the field of image.)

常规的中值滤波器，在噪声的密度不是很大的情况下效果不错。但是当概率出现的概率较高时，常规的中值滤波处理后，仍然具有噪声点，并丢失了细节和边缘，效果不是很好。 自适应中值滤波器可以尽可能的保护图像中细节信息，避免图像边缘的细化或者粗化。(The conventional median filter works well when the noise density is not very large. However, when the probability of probability is high, the conventional median filter still has noise points, and the details and edges are missing. The result is not very good. The adaptive median filter can protect details in the image as far as possible and avoid thinning or coarsening of the image edges.)

说明：  在地震处理中，非常经典的进行时深转换的程序，通常比较好用(In seismic processing, the very classic procedure for time-depth conversion, usually more useful)

Mallat算法和Atrous算法实现任意一维信号和二维图像的分解与重构。(Mallat algorithm and Atrous algorithm to achieve the arbitrary one-dimensional signals and two-dimensional image decomposition and reconstruction.)

说明：  多尺度retinex算法的matlab程序，用着不错(The matlab program of multi-scale Retinex algorithm is well used)
