REC.2100-HLG color space introduction

Also known as the REC.2100-HLG color space.There are 3 channels in total, Red,range from 0 to 1.Green,range from 0 to 1.Blue,range from 0 to 1.
Rec. 2100 HLG (Hybrid Log-Gamma) is an HDR standard developed by the BBC and NHK, designed for broadcast television. It supports a wide range of brightness levels for more realistic and dynamic imaging.
Rec. 2100 HLG color space.
In the Rec. 2100 HLG color space, colors are represented through Red (R), Green (G), and Blue (B) channels, adapting to different brightness levels of HDR displays.
Rec. 2100 HLG is primarily used in broadcast television supporting HDR, and it is backward compatible with standard dynamic range (SDR) displays.
The backward compatibility of Rec. 2100 HLG allows the same content to be displayed on both HDR and SDR displays without needing different versions.

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.
