HSI to CubeHelix 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.

CubeHelix color space introduction

Also known as the CubeHelix color space.There are 3 channels in total,Hue,commonly referred to as h,range from 0 to 360.Saturation,commonly referred to as s,range from 0 to 4.614.Lightness,commonly referred to as l,range from 0 to 1.
The CubeHelix color space was designed by Dave Green to create gradients that are visually uniform in both color and greyscale.
Known as the CubeHelix color space.
A color gradient is created by defining a starting hue and number of rotations while controlling changes in brightness and saturation to ensure visual consistency when converted to greyscale.
CubeHelix is particularly suited for scientific visualization, especially when images need to be converted to greyscale for printing or viewing by individuals with color vision deficiencies.
The advantage of CubeHelix lies in its ability to produce gradients that are continuous and uniform in both color and brightness, avoiding the jumps in brightness or color distortions often encountered in other color spaces.
