Chapter 5 Image Restoration and Reconstruction 图像复原与重建 5.1 A Model of the Image Defradation/Restoration Process 图像退化/复原过程的模型 As Fig.5.1 shows,the degradation process is modeled as a degradation function (退化函数) with an additive noise term (加性噪声) ,oper…
Consider a real LTI system with a WSS process $x(t)$ as input and WSS process $y(t)$ as output. Base on the WSS correlation properties,we get these equations $\begin{align*}&Time-Domain &:&R_{yy}(\tau) &= h(\tau)*h(-\tau)*R_{xx}(\tau)\\&a…
Awesome Courses Introduction There is a lot of hidden treasure lying within university pages scattered across the internet. This list is an attempt to bring to light those awesome courses which make their high-quality material i.e. assignments, lect…
这篇blog,原来是西弗吉利亚大学的Li xin整理的,CV代码相当的全,不知道要经过多长时间的积累才会有这么丰富的资源,在此谢谢LI Xin .我现在分享给大家,希望可以共同进步!还有,我需要说一下,不管你的理论有多么漂亮,不管你有多聪明,如果没有实验来证明,那么都是错误的. OK~本博文未经允许,禁止转载哦! By wei shen Reproducible Research in Computational Science “It doesn't matter how beautif…
上篇(webRTC中语音降噪模块ANS细节详解(二))讲了ANS的处理流程和语音在时域和频域的相互转换.本篇开始讲语音降噪的核心部分,首先讲噪声的初始估计以及基于估计出来的噪声算先验信噪比和后验信噪比. 1,初始噪声估计 webRTC中ANS的初始噪声估计用的是分位数噪声估计法(QBNE,Quantile Based Noise Estimation),对应的论文为<Quantile Based Noise Estimation For Spectral Subtraction And Wien…
