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.

There are several published color spaces such as YCrCb, DCT, DHT, YIQ, two approximate K-L transforms (K1K2K3 and KLT), the original reversible color transform (ORCT) adopted in JPEG-2000, YUV, YPrPb, CIE-UVW and CIE X-Y-Z to make the image processing algorithm more efficient than in the RGB space, so as to suitable for particular application.
The main plant recognition methods are : gaussian distribution models; near infrared images; texture ; shape features; spectral properties of reflection; spatial frequency based properties; dichromatic reflection model; other wavebands; RGB (red, green, blue) colour model; HSV(hue, saturation, value) colour space; YCrCb colour space (Klose et al, 2005); Grey Level Co-occurrence Matrix (GLCM); Fast Fourier Transform (FFT); Scale Invariant Feature Transform (SIFT); binarization; EGRBI transform (Excessive Green, RedBlue, Intensity) (Maksimow et al, 2007); Minimum Distance Function (MDF); clustering; seed mapping.
The SoC can be programed to output images in 8 bit CCIR 656 (YCrCb) or 565-RGB format.

YCrCb color space is adopted and contributes 192 coefficients (64Y, 64Cr, 64Cb) in the feature set which is used to index images.
It is said to be the first automotive monitor suitable for handling the digital interface between the YUV (YcrCb)-format DVD output and the display, offering exceptional contrast and color to optimize the performance and value of in-vehicle entertainment systems.
