yuv converter

Yuy2 is often used in TV systems and output formats of many cameras. during processing, we often need to convert it to RGB for processing. Here we will briefly introduce the Conversion Relationship Between yuy2 (YUV) and RGB: Http://msdn2.microsoft.com/en-us/library/ms893078.aspx Yuy2 (YUV) to RGB: C = Y-16 D = u-128 E = V-128 R = clip(( 298 * C + 409 * E + 128) >> 8)G = clip(( 298 * C - 100 * D

The reason is: The ddrawsurface is lost, and the ddraw surface is lost in many cases (for example, when other full-screen exclusive programs, screen saver, or screen lock programs are started ), surface loss is actually the memory or video memory used on the surface is released by the DirectDraw system and allocated to other programs. if the surface is lost, all operations on the surface will return dderr_surfacelost. At this time, you should call the idirectdrawsurface interface method restor

RGB and YUV Multimedia programming First, the concept 1. What is RGB? The method of encoding a color is collectively called " Color space " or " gamut ." In the simplest terms, the "color space" of any color in the world can be defined as a fixed number or variable. RGB (red, green, blue) is just one of many color spaces. With this coding method, each color can be represented by three variables-red green and the intensity of the blue. RGB is one of

1 PrefaceIn order to give color a quantitative measure, it is necessary to establish a color space model to describe a variety of colors, because people's perception of color is a complex process of physiological and psychological joint action, so in different fields of application in order to better and more accurately meet their needs, There are a variety of color space models to quantify the descriptive colors. We are more often exposed to include rgb/cmyk/yiq/

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

There is a field in the action that is of the birthday or date type. When we pass the value, it must be written as to automatically convert the type, however, in some cases, you may need to write 19990101 so that automatic type conversion is not performed by default. In this way, you can write a custom type converter to achieve conversion. Struts2 has two types of converters: Partial: it applies to an action conversion type. First, you need to customi

Tip: RGB and YUV----excerpt from the DirectShow Practice collection Author: Lu Qiming Computer color display the principle of color display and color TV, is the use of R (Red), G (Green), B (Blue) additive blending principle: By emitting three different intensity of the electron beam, so that the inside of the screen covered with red, green, blue phosphorescent material to produce color. The representation of this color is called the RGB color space

1 Overview YUV is a color encoding method. It is developed to be compatible with black and white TVs. In Modern Color TV systems, three-channel color cameras or color CCD cameras are usually used to retrieve images, and then the acquired color image signals are divided by color, respectively amplified and corrected to obtain RGB, then, the Brightness Signal y and two color difference signal R-Y (U) and B-Y (v) are obtained through Matrix Transform cir
