如何创建某些（R，G，B）色OPENCV图像并获得该颜色的名字吗？ [英] How to create openCV image of certain (R, G, B) color and get that color name?

问题描述

我需要创建填充有一些（R，G，B）的彩色图像。并获得该颜色的名字像一些（R，G，B）=黑色或红色等。我们可以做这样的事跟OpenCV的，怎么办呢？

I need to create an image filled with some (R,G,B) color. And get that color name like some (R,G,B) = black or red and so on. Can we do such thing with openCV, and how to do it?

推荐答案

OpenCV的不带颜色创建图像，最简单的办法是要么填充或只是绘制选定的颜色填充的矩形。结果
请参见 http://opencv.willowgarage.com/documentation/drawing_functions.html

opencv doesn't create images with a color, easiest way is either a fill or just draw a filled rectangle with the chosen color.
See http://opencv.willowgarage.com/documentation/drawing_functions.html

有没有（据我所知）一个返回颜色名称的功能，最简单的办法是从什么地方得到的颜色列表并检查RGB值对像素。如果你需要一个最接近的，而不是精确匹配（rememebr有名字并非所有244bit的颜色！）看HSV空间

There isn't (AFAIK) a function to return the color name, easiest way is to get a list of colors from somewhere and check the RGB values against the pixel. If you need a closest rather than exact match (rememebr there aren't names for all 244bit colors!) look at HSV color space
