以心电信号为例，利用小波变换模极大重建原信号(Reconstruction of the original signal using wavelet transform modulus maxima)

说明：  为了在抑制噪声时尽可能保留图像边缘信息，提出一种自适应各向异性高斯滤波器设计方法. 该方法由独立 强度传播（IDS）模型决定滤波器的长轴尺度，由像素的邻域平滑度决定长短轴的比例，然后根据该处的灰度梯度方 向自适应决定各向异性滤波器的长轴方向. 仿真实验表明，提出的自适应各向异性滤波器具有很强的噪声抑制和 边缘保持能力. (In order to suppress noise, as far as possible to keep the image edge information, an adaptive anisotropic Gaussian filter design methods. The method by the independent strength spread (IDS) model determines the long axis of the filter scale, the pixel neighborhood smoothness determine the ratio of minor axis, and then there' s gray gradient direction of adaptive decision the long axis of anisotropic filter. Simulation results show that the proposed adaptive anisotropic filter has a strong noise suppression and preserve edges.)

可以对点云添加噪声，对从网站上下载的标准点云研究提供基础数据，比如研究去噪方法，可通过添加噪声形成基础数据(You can add noise to the point cloud to the standard point cloud research downloaded from the website to provide basic data, such as research de-noising method can form the basis of the data by adding noise)

实现DCT与DWT相结合的算法,用matable及小波变换实现所想构思。(The algorithm of combining DCT with DWT is realized, and the idea is realized by matable and wavelet transform.)

说明：  利用97小波变换进行图像压缩，用matlab仿真，实验证明它具有较高的压缩比(using wavelet transform image compression using Matlab simulation experiment to prove that it has a higher compression ratio)

这篇文字介绍了基于IBP重建的图像超分辨算法(this paper introduce an super-resolution Algorithm based on IBP)

matlab环境下 建立单高斯模型，检测出运动的人体，后期经过数学形态学处理，效果很好。(matlab environment to establish a single Gaussian model, to detect the movement of the human body, the latter mathematical morphology after treatment, the effect well.)

很有用的gdal库，并且已经编译好。请多多指教!(It is a very good resource！Please download！！)

简单的帧间差分法，不过可以和其他方法结合来改进算法(A simple inter-frame difference method, but other methods can be combined to improve the algorithm for)

先进行图像的预处理，采用中值滤波，梯度增强。基于边缘帧差法实现前景检测(first image preproceing，the median filtering，grdient enhancement。based on edge detection method of frame to realiase prospect)
