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

JPEG color space introduction

Also known as the JPEG color space.There are 3 channels in total, Y,range from 0 to 255.Cb,range from 0 to 255.Cr,range from 0 to 255.
The JPEG standard was created by the Joint Photographic Experts Group and was officially published as an ISO standard in 1992.
JPEG, which stands for Joint Photographic Experts Group. The file format is typically .jpg or .jpeg.
The compression method involves transforming the image to a frequency domain using a Discrete Cosine Transform (DCT), quantizing the frequency components, and then encoding the result. JPEG images also support various levels of compression, which can be adjusted to balance image quality and file size.
JPEG is ubiquitous in digital photography, web graphics, and online image sharing due to its efficient compression methods.
JPEG uses a lossy compression technique, which means that some image quality is lost in the compression process, but the reduced file size is useful for storage and bandwidth considerations.

LABh(hunter-lab,hlab) color space introduction

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.
