Difference of Gaussian(DOG)是高斯函数的差分。 它是可以通过将图像与高斯函数进行卷积得到一幅图像的低通滤波结果,即去噪过程, 这里的Gaussian和高斯低通滤波器的高斯一样,是一个函数,即为正态分布函数。 同时,它对高斯拉普拉斯LoG的近似,在某一尺度上的特征检测可以通过对两个相邻高斯尺度空间的图像相减,得到DoG的...
Difference of Gaussian(DOG)是高斯函数的差分。我们已经知道可以通过将图像与高斯函数进行卷积得到一幅图像的低通滤波结果,即去噪过程,这里的Gaussian和高斯低通滤波器的高斯一样,是一个函数,即为正态分布函数。 那么difference of Gaussian 即高斯函数差分是两幅高斯图像的差, 一维表示: 二维表示: 具体到图像处理来讲...
差分金字塔,DOG(Difference of Gaussian)金字塔是在高斯金字塔的基础上构建起来的,其实生成高斯金字塔的目的就是为了构建DOG金字塔。 DOG金字塔的第1组第1层是由高斯金字塔的第1组第2层减第1组第1层得到的。以此类推,逐组逐层生成每一个差分图像,所有差分图像构成差分金字塔。概括为DOG金字塔的第o组第l层图像是有...
【DoG角点检测】DoG(DifferenceofGaussian)是灰度图像增强和角点检测的方法,其做法较简单,证明较复杂,具体讲解如下:DifferenceofGaussian(DOG)是高斯函数的差分。我们已经知道可以通过将图像与高斯函数进行卷积得到一幅图像的低通滤波结果,即去噪过程,这里的Gaussian和高斯低通滤波器 ...

The Oriented Difference of Gaussians (ODOG) model of brightness (perceived intensity) by Blakeslee and McCourt (Vision Research 39:4361-4377, 1999 ), which is based on linear spatial filtering by oriented receptive fields followed by contrast normalization, has proven highly successful in ...
Recent extensions to the standard difference-of-Gaussians (DoG) edge detection operator have rendered it less susceptible to noise and increased its aesthetic appeal. Despite these advances, the technical subtleties and stylistic potential of the DoG operator are often overlooked. This paper offers a...
DoG (Difference of Gaussian)实现角点检测。效果见http://blog./abcjennifer/article/details/7639488#comments
In this paper, a novel edge-based active contour method is proposed based on the difference of Gaussians (DoG) to segment intensity inhomogeneous images. DoG is known as a feature enhancement tool, which can enhance the edges of an image. However, in the proposed energy functional it is use...
