数字图像处理常见问题及编程技巧汇编。希望对这方面的学习者有所帮助(Data, the software architect exam is a comprehensive commo)

实现了立体匹配的SAD算法计算视差图，结果比较理想(Using the SAD algorithm to calculate the disparity map of stereo matching, the result is good.)

基于Canny算子检测图像边缘，其中含有非极大值抑制功能。(Based on Canny operator edge detection image, which contains a non-maxima suppression.)

Opencv处理图像，用ostu法实现图像的二值化(Opencv image processing, using ostu method to achieve image binarization)

说明：  基于四元数的matlab处理工具包，利用四元数实现了很多图像处理的功能，并提供了api供大家使用(Quaternion-based processing tool kit of matlab, the use of quaternions to achieve a lot of image processing functions, and to provide for your use of the api)

说明：  使用log-Gabor滤波器对图像进行滤波程序。(The use of log-Gabor filter image filtering process.)

KSVD工具包,可以用于去噪增强等多种领域,具体方法是先训练方向,然后沿方向进行(KSVD toolkit can be used to enhance various areas of de-noising, the specific method is the first training direction, and then along the direction)

本程序对同一图像增加噪声后，进行均值滤波、高斯平滑滤波和中值滤波三种方法的去噪和结果比较， 并进行了评价指标PSNR和SSIM的计算以及算法耗时的统计。 ( The program on the same image after the noise increases, mean filter, de-noising and results of the Gaussian smoothing filter and median filter three methods of comparison, and the index PSNR and SSIM calculation algorithm and time-consuming statistics.)

4_1：生成模糊化实验图像 4_2：维纳滤波复原 4_3：约束最小二乘滤波复原 4_4：Lucy-Richardson滤波复原 4_5：盲卷积滤波复原(4_1: generate fuzzy images of experimental 4_2: 4_3 restoration Wiener filtering: constrained least squares filtering recovery 4_4: Lucy-Richardson filter recovery 4_5: Blind deconvolution filter to recover)

自适应中值滤波器 该滤波器与中值滤波器相比，功能有很大的改善，但函数要复杂了很多(adapt median filter ,this filter compared with median filter, it is much improved in the resulted image.)
