问题描述
HSL是否比HSI和HSV优越，因为它考虑了人类的感知。
对于某些图像处理算法，他们说我可以使用这些颜色空间中的任何一个，即
，我不确定该选择哪个颜色空间。我的意思是，算法只是在乎为您提供
色相和饱和度通道，您可以选择要使用的色彩空间
Is HSL superior over HSI and HSV, because it takes human perception into account.?For some image processing algorithms they say I can use either of these color spaces,and I am not sure which one to pick. I mean, the algorithms just care that you providethem with hue and saturation channel, you can pick which color space to use
推荐答案
哪个最好，很大程度上取决于您使用它的目的。但是根据我的经验，HSL（HLS）在亮度和饱和度之间存在不幸的相互作用。
Which one is best very much depends on what you're using it for. But in my experience HSL (HLS) has an unfortunate interaction between brightness and saturation.
在此示例将图像亮度降低2。接下来是使用RGB，HLS和HSV的结果：
Here's an example of reducing image brightness by 2. The leftmost image is the original; next comes the results using RGB, HLS, and HSV:
请注意，HLS中蝴蝶边缘周围的亮度过高和饱和，尤其是底部的红色斑点。这就是我所指的饱和问题。
Notice the overly bright and saturated spots around the edge of the butterfly in HLS, particularly that red spot at the bottom. This is the saturation problem I was referring to.
此示例是使用进行转换。
This example was created in Python using the colorsys module for the conversions.
