正如卷积有线性卷积(linear convolution)和循环卷积(circular convolution)之分;互相关也有线性互相关(linear cross-correlation)和循环互相关(circular cross-correlation)。线性互相关和循环互相关的基本公式是一致的,不同之处在于如何处理边界数据。其本质的不同在于它们对原始数据的看法不同。通过这篇文章,我想整理一下...

The filter is based on a convolution filter, with approximate Gaussian kernels, hS and hW, for the indicator and width fields, respectively. The kernel size of the indicator field filter radius is based on the scalar rsc and the input width filter radius rMin. On lines 23–28 the starting...
This is a toolbox of useful matlab functions for geometry processing. There are also tools related to constrainted optimization and image processing. Typically these are utility functions that are not stand alone applications. Here's an incomplete list of cool features this matlab toolbox contains:...
I think the arc is too short to get a good elliptical fit. Why not a circular fit? Qualitatively at least, it looks pretty good:... 13 days ago | 0 Answered Why does this special case for associativity of a matrix product with a hadamard product hold true?
