一种改进的VIBE运动目标检测算法，属于背景差分法，能对不同环境的目标进行检测，能消除鬼影。(The moving target detection algorithm VIBE belongs to background difference method. It can detect objects in different environments and eliminate ghosts.)

vmd分解之后分解信号和原信号的对比图、频谱图等(After VMD decomposition, the contrast and spectrum of the decomposed signal and the original signal, etc.)

说明：  Hu矩定位图像，可以提取图像的特征，然后进行匹配定位(Hu Moment positioning images, can be extracted image features, and then proceed to match the positioning)

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)

利用随机霍夫变换进行圆的检测，matlab编写(Randomized Hough transform for circle detection, Matlab prepared)

这是一篇毕业论文基于小波图像去噪的方法研究(This is a thesis research methods based on wavelet image denoising)

SPIHT的图像压缩算法源代码。可以针对128×128的图像进行压缩(SPIHT image compression algorithm source code. 128 × 128 image compression)

说明：  chrounx是matlab的一个工具包(a toolbox for matlab)

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：  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.)
