Among them, gesture detection and recognition technology, as a new natural, simple and direct technology, is highly valued. In recent years, there have been considerable part of the application using this gesture recognition approach as a means of an interaction with the machine, and it draws attention of and was favored by the scientific research and technology enterprises of various countries. Computer vision-based gesture recognition needs to solve a series of problems. The first is is how to split the hand from the background; then separate the useful information and redundant one, and extract the relevant information gesture; finally, decipher the specific meaning of the same gesture in accordance with the actual situation. To solve these problems, this paper discusses a gesture recognition interactive system with a kind of background separation methods based on specific color model, and a kind of gesture extraction method on key information, developed by Visual C + + 2010 and OpenCV, fits a variety of camera, which includes the following aspects: (1) For different quality defects among cameras, this system uses median filter or mean filter and restores the detail method to reduce the image noise conservatively. Then use different sampling radius of USM sharpening to enhance the image information. (2) According to the difference of colors between background and hands, this system uses the brightness and the two color channels as a color model for color separation. The not chosen distinct, such a
