Video application system, video special effect processing system and method

Abstract

The invention provides a video special effect processing system comprising a video collecting module, a face detection module, a video special effect module and a video scaling module, wherein the video collecting module is used for collecting first resolution video data; the face detection module is used for carrying out face detection on the first resolution video data to extract face parameter; the video special effect module is used for carrying out special effect processing on the first resolution video data by utilizing the extracted face parameters; and the video scaling module is used for zooming out the first resolution video data subjected to the special effect processing into the second resolution video data, wherein a second resolution is less than a first resolution. On one hand, because the face detection is carried out based on a high resolution image, a more accurate face detection effect can be obtained; on the other hand, because the high resolution image is zoomed out to form a low resolution image suitable for transmission of instant communication software, the stable transmission of the video image can be ensured.

Description

【Technical field】 [0001] The invention relates to the field of image processing, in particular to a video application system, a video special effect processing system and method. 【Background technique】 [0002] With the rapid development and application of the Internet, various multimedia services have also been widely used, and video chatting is one of the very important multimedia services, especially when the network speed is relatively fast and the video technology of instant messaging software is relatively mature. , people are more keen on video chatting. [0003] At present, in order to enhance the fun of chatting, some chatting software or chatting cameras have the function of detecting faces in the video, and adding some interesting photo frames and masks according to the position of the faces. In order to save network bandwidth and increase the video frame rate, instant messaging software (IM) usually uses a small resolution of 160*120 (QQVGA) or 320*240 (QVGA) fo...

AI Technical Summary

Problems solved by technology

In specific use, it may appear that the special effect picture does not fit completely according to the position of the face or the face is not detected.

On the other hand, the current mainstream cameras can collect video data with a resolution above VGA (640*480) or VGA (such as 1280*960) in terms of physical performance. The above-mentioned solutions do not make full use of the physical performance of the camera.

[0004] In view of this, it is necessary to provide a new solution to solve the defects of low accuracy of face detection in the above usage scenarios
