HSI, HSV, and HSL are all different color spaces. Hue computation is (as far as I can find) identical between the three models, and uses a 6-piece piece-wise function to determine it, or for a simpler model that is accurate to within 1.2 degrees, atan((sqrt(3)⋅(G-B))/2(R-G-B)) can be used. For the most part, these two are interchangeable, but ...

2015年1月28日 · HSI contains hue and saturation, which are the terms that people use to describe colors. On the other hand, hue and saturation are angles, which can be inconvenient for computing distances in the color space.

2018年7月20日 · Here's a comparison between HSV / HSL / HSI color spaces. I think it's important to keep in mind that these models come from a projection of the RGB cube. For more details on this, check the Wikipedia page (specially this figure) and this answer on Stack Overflow. Hue. Their hues are approximately the same. For HSI [1]:

2017年4月27日 · According to the Wikipedia article given HERE, the HSV, HLS and HSI color space terminology can be used interchangeably. There is another option available in OpenCV as well cv2.cvtColor(img1,cv2.COLOR_BGR2HSV). If you work out both the options, the resulting image would appear slightly different as in the following: Using HSV: Using HLS:

2012年6月28日 · I am reading a book for image processing algorithms and for the contrast algorithm it says that I can either go RGB->HSL or RGB->HSI first and than apply a contrast technique for grayscale images, ...

2019年10月17日 · Unlike the RGB and CMYK color models, Lab color is designed to approximate human vision. It aspires to perceptual uniformity, and its L component closely matches human perception of lightness That is the reason that many computer vision algorithms are taking advantage of LAB space

2012年12月19日 · at the current state of your program the HSI valus are computed but not used. So in order to see whether the computation succeeds or produces bogus results, I just wrote them back into the image to visualize them as RGB-values.

2018年10月23日 · Which tells you the ranges that it should be in... In your case, the HSI values go from 0-360 in the Hue which will be clipped to 255 any value above it. That is one of the reasons why OpenCV uses the Hue range from 0-180, to be able to fit it inside the range. Then the HSI->RGB seems to return the image in float, then it will be clipped in 1.0.
