何时在Emgu CV中使用“图像"以及何时使用“矩阵"? [英] When to use `image` and when to use `Matrix` in Emgu CV?

问题描述

在openCV中，我几乎经常使用cv::Mat进行所有操作.现在，我需要使用emgu CV并在stat中使用Matrix -object，但是不支持某些功能?！...我可以改用image -class吗?

in openCV I regularly use cv::Mat for almost everything. Now, I need to use emgu CV and use the Matrix-object in stat, but some functions are not supported?!... may I use the image-class instead?

何时在emgu CV中使用image和何时使用matrix?

When to use image and when to use matrix in emgu CV?

P.S .:目前，我正在寻找一种在矩阵上定义ROI的方法，但没有找到一种无需复制数据的方法.

P.S.: Currently I'm looking for a way to define a ROI on a matrix but didn't find a way without copying the data.

版本:Emgu.CV-2.4.2

推荐答案

我知道在最新版本的OpenCV中，对于

I know that in the latest version of OpenCV, the Mat object is prefered to iplImage for a lot of reasons.

在EmguCV中，情况有所不同.我认为经验法则是当数据本身应该是图像时使用Image<>，而当您需要使用矩阵时则使用Mat<>.使用所需的东西，emguCV对象应具有适合您的需求的构造函数/功能.

In EmguCV, things are different. I think that the rule of thumbs is to use Image<> when the data itself is supposed to be an image and Mat<> when you need to work with a matrix. Work with what you need and the emguCV object should have the right contructor/function for your needs.

对于ROI，sumeet的评论非常好.

For the ROI, the comment by sumeet is very good.
