To collect and process videos, you must learn to analyze YUV data. From the collection point of view, generally the video capture chip output streams are generally in the form of YUV data streams, while video processing (such as H. 264. MPEG Video Codec) is also used for encoding and parsing the original YUV code stream. Therefore, it is important for people who are engaged in the video field to understand how to analyze the YUV data stream. This article briefly introduces how to analyze YUV dat

YUV is mainly used to optimize the transmission of color video signals, so that it is backward compatible with vintage black and white TVs. Compared with RGB video signal transmission, RGB requires three independent video signals to be transmitted at the same time. In YUV, "Y" indicates the brightness (luminance or Luma), that is,

Statement: This article Reprinted from: http://www.cnblogs.com/azraelly/archive/2013/01/01/2841269.html YUV formats include planar and packed.For the YUV format of planar, the y of all pixels is stored consecutively, followed by the U of all pixels, followed by the V of all pixels.For the packed YUV format, the Y, U, and V of each pixel are stored consecutively. YUV is divided into three components. "Y" indicates the brightness (luminance or Luma), that is, the gray value; "u" and "V" represe

adopted by multiple electronic and electrical appliance manufacturers is to Convert RGB to YUV to maintain compatibility, and then switch back to the RGB format as needed, to display color images on computer monitors. Rgb24 indicates that the R, G, and B components each occupy 8 digits. Rgb32 indicates that the four components R, G, B, And a each occupy 8 digits. When you edit the color in the appearance of Windows desktop properties, there are two ways to edit the color: YUV and RGB. YUV is ma

grayscale of images :The process of transforming color images into grayscale images becomes the grayscale processing of images. The color of each pixel in a color image is determined by the R, G, and b three components, and each component has a value of 255, so that a pixel can have a range of more than 16 million (255*255*255) color variations. and gray image is R, G, b three components of a special color image, the range of one pixel change is 255, so in the digital image processing species ge
