LAB(cielab) to HSI Converter - Color Space Converter

LAB(cielab) color space introduction

Also known as the LAB(cielab) color space.There are 3 channels in total, lightness,range from 0 to 100.a,range from -100 to 100.b,range from -100 to 100.
Defined by the International Commission on Illumination (CIE) in 1976, as an improvement and extension of the CIE XYZ color space, designed to be a closer approximation to human visual non-linearity.
Commonly known as CIELAB color space, abbreviated as L*a*b* or Lab.
Lab colors are typically represented by three coordinates: L* for lightness, a* for green to red chromaticity, and b* for blue to yellow chromaticity. They can be algorithmically converted to other color spaces for display or printing on different devices.
The Lab color space is extensively used in color measurement and management, particularly important in fields requiring precise color matching and assessment such as digital printing, photography, image analysis, and industrial color testing.
The advantage of the Lab color space lies in its device independence, allowing for consistent and accurate color conversion across different devices and software.

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.
