基于双边滤波的retinex图像增强算法(Retinex Algorithm for Image Enhancement Based on Bilateral Filtering)

傅里叶梅林变换实现图像配准，对旋转，缩放，剪切，平移都有效(Fourier Mellin Transform for image registration, valid for rotation, scaling, cropping, shifting)

一种基于孔径编码的图像复原方法，效果非常好，不过缺陷是需要知道PSF等先验知识(Based on coded aperture image restoration method, the effect is very good, but the deficiencies need to know a priori knowledge of PSF, etc.)

说明：  example used in Python & VTK

一般自然图像的梯度分布符合重尾分布，重尾分布也就是超拉普拉斯分布，根据这个特点进行图像复原。(The gradient of a natural image in line with heavy-tailed distribution, which is ultra-heavy-tailed distribution Laplace distribution, image restoration based on this feature.)

RANSAC算法实现数据拟合，用此算法可以实现多视角图像匹配等(RANSAC algorithm for data fitting, using this algorithm can realize multi-angle image matching, etc.)

说明：  读图然后根据图像的对象，进行边缘检测，椭圆拟合(Read the image and then carry out edge detection and ellipse fitting according to the object of the image)

运用图聚类实现SAR图像的分割，效果明显，程序简洁。(the segmentation of SAR)
