高斯滤波(Gauss filter)实质上是一种信号的滤波器,其用途为信号的平滑处理,数字图像用于后期应用,其噪声是最大的问题,因为误差会累计传递等原因,大多图像处理教材会在很早的时候介绍Gauss滤波器,用于得到信噪比SNR较高的图像(反应真实信号)。高斯平滑滤波器对于抑制服从正态分布的噪声非常有效。 原理 编辑 图像大多数噪...
MATLAB - Laplacian of Gaussian Filter - A Gaussian filter is a linear filter used in image processing to blur or smooth images. It is named after the Gaussian function, which is used to define the filter's shape. The Gaussian filter is commonly used to r

while the image is getting smaller and smaller. This inevitably leads to a situation where the image size is smaller than the filter size. So, I used these two functions to give a simple example to see if they can work properly.
We describe the Gaussian filter and its implementation in this chapter. The time domain representation (or the weighting function) of the filter is provided. The frequency domain representation (or the transmission characteristics) is also provided. Examples in this chapter show how the time and fre...

Introduction to gaussian filter 高斯滤波器 Introduction to gaussian filter 我尝试尽可能低门槛的介绍这些好玩的东东～这里只须要正态分布函数作为基础就可以開始玩图像的高斯滤波了. Don't panic ! 在通常的图像中,像素点都非常多,非常多情况都是非常多一大块像素点记录某一个场景区域。那么这就数字离散环境下...

是matlab里的函数吧？在matlab的help文档里搜fspecial这个函数的加高斯噪声的说明，具体的原文说明如下：h = fspecial('gaussian', hsize, sigma) returns a rotationally symmetric Gaussian lowpass filter of size hsize with standard deviation sigma (positive). hsize can be a vector specifying the...
