ICTCP to LABh(hunter-lab,hlab) Converter - Color Space Converter

Also known as the ICTCP color space.There are 3 channels in total, I,range from 0 to 1.CT,range from -0.5 to 0.5.CP,range from -0.5 to 0.5.

The ICtCp color representation model was developed for high dynamic range (HDR) and wide color gamut (WCG) media, representing I (Intensity), Ct (Chroma of red-green), and Cp (Chroma of blue-yellow).

ICtCp color space.

In the ICtCp color space, colors are represented through Intensity (I), Chroma of red-green (Ct), and Chroma of blue-yellow (Cp).

ICtCp is primarily used for HDR and WCG video formats, intended to replace the YCbCr color space, offering better color difference encoding and improved efficiency for these advanced video applications.

The ICtCp color space is particularly suitable for handling HDR and WCG video content, providing a color representation that aligns more closely with human visual perception.

Also known as the LABh(hunter-lab,hlab) color space.There are 3 channels in total,lightness,range from 0 to 100.a,range from -128 to 128.b,range from -128 to 128.

Developed by Richard S. Hunter in the 1940s as a color scale based on opponent-color theory. It is an adaptation of the CIE XYZ color space to be more perceptually linear.

Often referred to as Hunter Lab, or Lab Hunter.

Colors in the Hunter Lab color space are expressed through three coordinates: L (for lightness), a (red/green value), and b (blue/yellow value). These are calculated from CIE XYZ using Hunter's specific equations.

Hunter Lab is used in various industries for color matching, quality control, and other applications where a perceptually linear space is beneficial for color difference measurement.

Although similar to CIELAB, the Hunter Lab color space is used less frequently in contemporary applications. However, it remains significant in industries that adopted it early on and continue to rely on its specific color-rendering properties.
