OSA-UCS to YCgCo Converter - Color Space Converter

Also known as the OSA-UCS color space.There are 3 channels in total, L,range from -10 to 8.j,range from -6 to 12.g,range from -10 to 6.

The OSA-UCS color space was developed by the Optical Society of America in the 1970s with the goal of creating a color space that provided a more uniform appearance than the CIE 1931 XYZ color space.

The OSA-UCS color space, also known as the Optical Society of America Uniform Color Scale.

Colors in the OSA-UCS color space are represented by three parameters: lightness (L), hue (J), and chroma (g).

OSA-UCS is used in the field of visual sciences for the research and precise measurement of color differences due to its uniformity.

The application of the OSA-UCS color space is relatively limited in the commercial sector, primarily because it is more complex to calculate and not as widely used as the CIELAB color space.

Also known as the YCgCo color space.There are 3 channels in total,Y,range from 0 to 1.Cg,range from -0.5 to 0.5.Co,range from -0.5 to 0.5.

Origin: The YCgCo color space was designed for digital video processing to provide a simple and reversible color transformation method, serving as an approximation of the YCbCr color space.

Primary Names: YCgCo color space, where 'Y' represents the luminance component, 'Cg' stands for the green difference component, and 'Co' represents the red-blue difference component.

Typically expressed as a triplet, for example: YCgCo(0.5, -0.25, 0.25) represents a color with specific luminance and chromatic differences.

Usage Scope: Mainly used in image coding and digital video processing, for example, it is applied in encoding standards such as JPEG XR and H.264/MPEG-4 AVC.

Additionally, due to the simple conversion process of YCgCo, it supports efficient hardware implementation and can be losslessly transformed back to the RGB format.
