如何使用 Node.js 比较两个图像 [英] How to compare two images using Node.js

问题描述

我正在寻找一种方法来比较两张图片，看看它们有多相似.谷歌搜索它会产生大量的图像处理结果(裁剪、调整大小等)，但无法对图像进行近似比较.有一个 Node.js 库，但它是 0.0.1 版本，并且依赖于各种 3rd 方系统包，因此不稳定或可移植.

I am looking for a way to compare two images to see how similar they are. Googling it produces tons of image processing results (cropping, re-sizing, etc.), but nothing that would do approximate comparisons of images. There is one Node.js library, but it is version 0.0.1 and relies on various 3rd party system packages, so not stable or portable.

类似的东西:

var imgComparator = require('some-awesome-image-comparator-module');
// result would be between 1.0 and 0.0, where 1.0 would mean exact match
var result = imgComparator.compare('/path/to/image/1.png', '/path/to/image/2.png');

推荐答案

有node-opencv 模块，您可以使用它来执行图像比较等繁重的操作.很好的主题在这里:简单快速的比较图像的方法相似度

There is node-opencv module, you might use it in order to perform heavy operation like image comparison. Good topic on that is here: Simple and fast method to compare images for similarity
