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.

Let [N.sup.[alpha]] denote the noisy image in YCbCr color space where [alpha][epsilon]{Y, Cb, Cr}; then matrix [M.sup.Y] of vectorized patches is constructed from the [N.sup.Y] component by extracting all overlapping patches O of size [square root of (E)] x [square root of (E)] as
Once the microscopic images are obtained from the blood smears, they are converted from the RGB color space to YCbCr [14], which allows better highlighting the nuclei of the globules present in the image with respect to other color spaces.
Many previous works have already focused on developing explicit content detection mechanism for media contents based on different techniques such as identification of skin region, skin detection, YCbCr space color, and HSV color model.

Therefore in our image enhancement method, we firstly transform the HDR pathology image into YCbCr color space (the type of sampling is 4: 4: 4), then divide the luminance component into base layer and detail layer by GIF rather than BF, next compress the dynamic range for base layer using histogram mapping to reduce noise and enhance detail information, meanwhile enhance the detail layer by adaptive masking, and finally combine the enhanced luminance component and color component together.
