HSI to UVW(cieuvw,cie1964) Converter - Color Space Converter

HSI color space introduction

Also known as the HSI color space.There are 3 channels in total, hue,range from 0 to 360.saturation,range from 0 to 100.intensity,range from 0 to 255.
Origin: The HSI color space was designed to better match the color perception characteristics of the human eye, suitable for processing color-related information.
Primary Names: HSI, which includes H (Hue), S (Saturation), and I (Intensity) as the three color channels.
Typically expressed as a triplet, for example: hsi(120°, 0.5, 0.75) represents a green hue with medium saturation and high brightness.
Usage Scope: Extensively used in image processing and analysis, such as color segmentation, edge detection, target tracking, etc.
Additionally, HSI can be converted to and from RGB, and while similar to HSV and HSL, in HSI, I (Intensity) represents the overall brightness of the color.

UVW(cieuvw,cie1964) color space introduction

Also known as the UVW(cieuvw,cie1964) color space.There are 3 channels in total,U,range from -134 to 224.V,range from -140 to 122.W,range from 0 to 100.
Developed by the CIE in 1964 as an improvement over the CIE 1960 UCS for better perceptual uniformity across different hues and lightness levels.
It is known as the CIE 1964 (U^*, V^*, W^*) color space, and commonly abbreviated as CIE UVW.
The color in the CIE UVW space is represented by three coordinates: (U^*), (V^*), and (W^*). These are calculated from the XYZ coordinates with a series of transformations intended to achieve a more uniform color space, taking into account the luminance factor.
The CIE UVW color space is used in specialized applications that require a uniform measure of color differences, such as in colorimetry research and the development of color standards.
The CIE UVW color space is less commonly used in practical applications today, having been largely replaced by more advanced color spaces like CIELAB and CIELUV, which offer better perceptual uniformity.
