说明：  用VB做的图像二值化的代码,希望能对大家有帮助(vb image test)

改进的剪切波变换，用于图像处理，分解层数多，运行速度快(Improved shear wave transform for image processing, decomposition of many layers, fast running speed)

A Drawable that manages an array of other Drawables. These are drawn in array order, so the element with the largest index will be drawn on top.

说明：  基于DCT和DWT的数字水印技术，可对图像进行DCT和DWT变换(Digital watermarking technology based on DCT and DWT can transform image into DCT and DWT)

本文实现了Retinex算法，支持对图像的去雾灯操作，是一种图像增强的方法。(this paper present a new image strength method-Retinex impliment by opencv)

说明：  基于matlab的快速非局部均值去噪的源程序(Source program of fast nonlocal mean denoising based on MATLAB)

TV模型属于图像处理领域里面的图像修复模型，对图像处理邻域的学习有很大的裨益(The TV model belongs to the image restoration model in the field of image processing, which is of great benefit to the study of image processing neighborhoods.)

医学图像分割是数字图像分析中的重要环节，是长期以来国内外研究的热点问题，本代码专注于血管图像领域的分割。(Medical image segmentation is an important part of digital image analysis, is a hot topic at home and abroad for a long time, this code is to focus on areas of blood vessel image segmentation method.)

说明：  在这个知识库中，图形信号处理的一些有趣的特性被表示出来。演示通过经典信号处理和图形信号处理对一维和二维欧几里得域信号应用低通滤波器，比较两种方法的结果。在此基础上，验证了图形信号处理的工作机制。此外，还描述了在非欧几里得域上滤波信号的示例。(In this repository, Some fascinating features of Graph Signal Processing were represented. Demos incudes applying a low-pass filter on both 1D and 2D euclidian domain signal by classical signal processing and also Graph signal processing to compare both results are the same. Within that way, we will validate the working mechanism of Graph Signal Processing. In addition to this, an example of filtering a signal on the non-euclidian domain was also represented.)
