A color is described as a Y′ component and two chroma components U and V. The prime symbol (') denotes that the luma is calculated from gamma-corrected RGB input and that it is different from true luminance. [1] Today, the term YUV is commonly used in the computer industry to describe colorspaces that are encoded using YCbCr. [2]
Pixel formats used in Y'CbCr can be referred to as YUV too, for example yuv420p, yuvj420p and many others. In a similar vein, the term luminance and the symbol Y are often used erroneously to refer to luma, which is denoted with the symbol Y'. The luma (Y') of video engineering deviates from the luminance (Y) of color science (as defined by CIE).
YCbCr is sometimes abbreviated to YCC.Typically the terms Y′CbCr, YCbCr, YPbPr and YUV are used interchangeably, leading to some confusion. The main difference is that YPbPr is used with analog images and YCbCr with digital images, leading to different scaling values for U max and V max (in YCbCr both are ) when converting to/from YUV.

The color observed is created entirely by the refractive properties of the flakes, analogous to the perception of rainbow colors in oil slicks. ChromaFlair paint has also been used as a substitute for optically variable ink in the use of counterfeiting the currency of the United States.
Certain types of headaches may be a sign of a more serious condition, such as a brain tumor or aneurysm, especially if the pain is sudden or severe, according to Cohen. "This highlights the ...
BRASILIA (Reuters) -Brazilian police on Tuesday arrested five people, including a member of former President Jair Bolsonaro's cabinet, suspected of involvement in an alleged plan to kill then ...
A color in the RGB color model is described by indicating how much of each of the red, green, and blue is included. The color is expressed as an RGB triplet (r,g,b), each component of which can vary from zero to a defined maximum value. If all the components are at zero the result is black; if all are at maximum, the result is the brightest ...
