非欧几里得域上滤波信号 balcilar-Graph_Signal_Processing
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.)

图像空域增强处理
说明： 思想：把原始图的直方图变换为均匀分布的形式，这样就增加了灰度值的动态
范围从而达到增强图像整体对比度的效果。其优点是能自动地增强整个 图像的对比度。
1、对灰度图像进行直方图的均衡化处理，达到图像增强的目的。
2、利用平均滤波和中值滤波对图像进行平滑滤波。
3、利用拉普拉斯运算对图像进行锐化滤波。(Idea: transform the histogram of the original image into the form of uniform distribution, so as to increase the dynamic gray value
Range to enhance the overall contrast of the image. Its advantage is that it can automatically enhance the contrast of the whole image.
1. The gray image is processed by histogram equalization to achieve the purpose of image enhancement.
2. Average filter and median filter are used to smooth the image.
3. Using Laplace operation to sharpen the image.)
