How does YUV color coding work?
In YUV, 'Y' represents the brightness, or 'luma' value, and 'UV' represents the color, or 'chroma' values. In contrast, the values of the RGB encoding scheme represent the intensities of red, green and blue channels in each pixel. Each unique Y, U and V value comprises 8 bits, or one byte, of data.
What color space is YUV?
As we know, RGB stands for red, blue and green and YUV stands for (Y) luma, or brightness, (U) blue projection and (V) red projection.
Why use YUV instead of RGB?
YUV color-spaces are a more efficient coding and reduce the bandwidth more than RGB capture can. Most video cards, therefore, render directly using YUV or luminance/chrominance images. The most important component for YUV capture is always the luminance, or Y component.
What are the three channels of information in the YUV color space?
The term YUV refers to a family of color spaces, all of which encode brightness information separately from color information. Like RGB, YUV uses three values to represent any color. These values are termed Y', U, and V.
