如何在numpy中进行卷积矩阵运算? [英] How to do convolution matrix operation in numpy?

问题描述

是否可以使用numpy进行卷积矩阵操作?

Is there a way to do convolution matrix operation using numpy?

numpy.convolve 仅在一维数组，所以这不是解决方案.

The numpy.convolve only operates on 1D arrays, so this is not the solution.

我宁愿避免使用scipy，因为在Windows上安装它似乎更加困难.

I rather want to avoid using scipy, since it appears to be more difficult getting installed on Windows.

推荐答案

您有scipy的 ndimage ，它允许您使用

You have scipy's ndimage which allows you to perform N-dimensional convolution with convolve:

from scipy.ndimage import convolve
convolve(data, kernel)

我知道您说过要避免臭皮……但我建议您不要这样做. Scipy在很多方面都很棒.如果要在Windows上安装它，请尝试已安装scipy的 Anaconda发行版.

I know that you said that you want to avoid scipy... but I would advise against it. Scipy is great in so many ways. If you want to install it on windows, try Anaconda Distribution, which already comes with scipy installed.

Anaconda是一个多平台的python发行版，它预先安装了所有必需的库(包括许多科学计算库)，并安装了pip或conda之类的工具来安装新库.不，他们不付钱给我做广告:/而是让您的多平台生活变得更加轻松.

Anaconda is a multiplatform python distribution that comes with all the essential libraries (including a lot of scientific computing libraries) preinstalled, and tools like pip or conda to install new ones. And no, they don't pay me to advertise it :/ but makes your multiplatform life much easier.
