HSV色彩空间和CvInRangeS函数 [英] HSV colour space and CvInRangeS function

问题描述

cvInRangeS(imgHSV, cvScalar(15, 234, 120), cvScalar(21, 234, 120), imgThreshed);

我想知道cvScalar函数中的每个参数代表什么.我认为这将是HSV，但它似乎并未达到所需颜色的阈值.有人可以更清楚地解释参数吗?

I am wondering what each parameter in the cvScalar function represents. I thought it would be HSV but it doesnt seem to be thresholding the desired color. Could someone explain the parameters a bit clearer?

推荐答案

意思是

H-色相，S-饱和度，V-值

H - Hue, S - Saturation, V - Value

在这里了解一下其中的每一个:

take a look in here for understanding each one of those:

颜色主要在色相组件中定义.这里有关于HSV空间阈值的很好的教程:

the color is mainly defined in the Hue component. There is a good tutorial about thresholding in HSV space in here:
