这样的话,那就不得不介绍HSV颜色空间了,H代表Hue(色彩),S代表Saturation(饱和度),V代表Value,也可用B表示(Brightness,明度),HSV空间也可称作HSB空间。 HSV空间在wikipedia上的介绍,https://en.wikipedia.org/wiki/HSL_and_HSV 下面根据自己的理解介绍一下HSV空间,以及其各通道在Matlab和OpenCV中的不同。 HSV的...

In this color space, the hue is represented as an angle on the color circle. Saturation goes from 0 (greyscale) to 100% (fully saturated colors) and value goes from 0 (black) to 1 (full brightness). For details see: Wikipedia. A Note on Implementation For performance reasons, DALI ...
蓝色原色:(0.1666,0.0089)(0.1666,0.0089) CIE RGB 的色域相对较大,但由于其原色不完全符合现代显示技术的需求,因此在实际应用中不如其他色彩空间(如 sRGB 和 DCI-P3)常用。 图片来自:https://zh.wikipedia.org/wiki/CIE_1931%E8%89%B2%E5%BD%A9%E7%A9%BA%E9%97%B4 CMYK 色彩空间: 目的:CMYK色域用于印...

I'm guessing you want to create a plot similar to the cone in the following Wikipedia image: One way to do this is to plot your cone and texture map the surface with an image of the HSV color space. Here's how you could do this: % First, create a 100-by-100 image to texture ...
2. http://en.wikipedia.org/wiki/HSL_and_HSV Inspect the color-space cylinder for HSL - it gives a very clear idea of the kind of distribution I've talked about. Plus, if you've dealt with paints at any point, the above explanation will (hopefully) make sense. :) Thus HSL is a...
