It has the luma "luminance" plane Y first, then the U chroma plane and last the V chroma plane. The two chroma planes (blue and red projections) are sub-sampled in both the horizontal and vertical dimensions by a factor of 2. That is to say, for a 2×2 square of pixels, there are 4 Y samples but only 1 U sample and 1 V sample.

The U-V plane has half as many lines as the Y plane. These two formats are the preferred 4:2:0 planar pixel formats for higher precision YUV representations. They are expected to be an intermediate-term requirement for DirectX Video Acceleration (DXVA) accelerators that support 10-bit or 16-bit 4:2:0 video.

1. Using the LUT values as described might be exactly how the Wikipedia article image was made but the description implies it's arbitrary and used maybe because it's simple. It isn't arbitrary; the results essentially match how RGB <-> YUV conversions work. If you are using OpenCV then the methods BGR2YUV and YUV2BGR give the result using the.

The U and V components, also called chroma values or color difference values, are derived by subtracting the Y value from the red and blue components of the original RGB color: U = B - Y' V = R - Y' Together, these values contain enough information to recover the original RGB value.

CIELUV. In colorimetry, the CIE 1976 L*, u*, v* color space, commonly known by its abbreviation CIELUV, is a color space adopted by the International Commission on Illumination (CIE) in 1976, as a simple-to-compute transformation of the 1931 CIE XYZ color space, but which attempted perceptual uniformity. It is extensively used for applications.

Example of U-V color plane, Y′ value = 0.5, represented within RGB color gamut An image along with its Y′, U, and V components respectively. Y′UV, also written YUV, is the color model found in the PAL analogue color TV standard (excluding PAL-N).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.

Each unique Y, U and V value comprises 8 bits, or one byte, of data. Where supported, our color camera models allow YUV transmission in 24-, 16-, and 12-bit per pixel (bpp) format. In 16 and 12 bpp formats, the U and V color values are shared between pixels, which frees bandwidth and may increase frame rate. Known as "chroma subsampling.

The Y in YUV stands for "luma," which is brightness, or lightness, and black and white TVs decode only the Y part of the signal. U and V provide color information and are "color difference.

With this theorem for double integrals, we can change the variables from (x, y) to (u, v) in a double integral simply by replacing. dA = dxdy = |∂(x, y) ∂(u, v)|dudv. when we use the substitutions x = g(u, v) and y = h(u, v) and then change the limits of integration accordingly.

An image along with its Y′, U, and V components respectively. YUV is a color model typically used as part of a color image pipeline. It encodes a color image or video taking human perception into account, allowing reduced bandwidth for chrominance components, compared to a "direct" RGB-representation. Historically, the terms YUV and Y′UV.

YUV pixel formats. YUV formats fall into two distinct groups, the packed formats where Y, U (Cb) and V (Cr) samples are packed together into macropixels which are stored in a single array, and the planar formats where each component is stored as a separate array, the final image being a fusing of the three separate planes.. In the diagrams below, the numerical suffix attached to each Y, U or V.

As shown in the above image, the Y', U and V components in Y'UV420 are encoded separately in sequential blocks. A Y' value is stored for every pixel, followed by a U value for each 2×2 square block of pixels, and finally a V value for each 2×2 block. Corresponding Y', U and V values are shown using the same color in the diagram above.
