YCbCr

One of two primary color spaces used to represent digital component video (the other is RGB). The difference between YCbCr and RGB is that YCbCr represents color as brightness and two color difference signals, while RGB represents color as red, green and blue. In YCbCr, the Y is the brightness (luma), Cb is blue minus luma (B-Y) and Cr is red minus luma (R-Y). See component video.

YCbCr Is Digital
MPEG compression, which is used in DVDs, digital TV and Video CDs, is coded in YCbCr, and digital camcorders (MiniDV, DV, Digital Betacam, etc.) output YCbCr over a digital link such as FireWire or SDI. The ITU-R BT.601 international standard for digital video defines both YCbCr and RGB color spaces. See chroma subsampling.

YPbPr Is Analog
YPbPr is the analog counterpart of YCbCr. It uses three cables for connection, whereas YCbCr uses only a single cable (see YPbPr). See YUV, YUV/RGB conversion formulas and ITU-R BT.601.

Henceforth, all the pixels of the original image (3) are surveyed and RGB pixels are converted into YCbCr (4) since the skin spectrum lies in YCbBr.

Designated TC90A92AFG, the highly integrated, high-performance comb filter front-end processor produces high picture quality digital YCbCr from the input of composite, S-video, or component video through the integration of 3D-YCS, 3L-YCS, 3D-YNR/CNR, digital multi-standard color decoding and picture improvement functions.
The ICM-205B also enables the output of different formats (including 8/16-bit YUV or YCbCr, 16-bit or 24-bit RGB and 8-bit raw data) for the best suitable interface with a cell phone or PDA controller for either embedded or accessory cameras.
AutoSense automatically synchronizes and adjusts the projector to incoming video, S-Video, RGB, YcbCr Component and HDTV computer and video signals.
In the field of shadow detection, Deb and Sunny [17] proposed a shadow detection and removal framework by using the luminance, chromatic blue, chromatic red from YCbCr color space to detect and remove shadows from images.
They compared ten different color spaces (RGB, CMY, YUV, YIQ, YPbPr, YCbCr, YCgCr, YDbDr, HSV or HSI and CIE-XYZ) and found that the most appropriate ones for skin color detection are HSV, YCgCr and YDbDr.
The advancement of the above detection method is that instead of YCbCr color space HSI color space is used for detection of white colored contaminants present in the cotton.
