Problems solved by technology

[0004] Because the method provided by the prior art has high requirements on the hardware of the equipment, and the hardware of mobile terminals such as smart phones and tablet computers cannot meet the hardware requirements of the method, the mobile terminal cannot use the method provided by the prior art for real-time video streaming. face beautification; at the same time, the overall effect of the existing beautified video is not good, and the visual perception effect of the face area is poor

Embodiment 1

[0042] Embodiment 1: as figure 1 As shown, the first purpose of the present invention is to provide a video beautification system applied to Internet video live broadcast, including:

[0043] Beautification unit 1, camera 2, face detection library 3 and display unit 4; camera 1 is used to obtain video frames, and face detection library 3 is used to detect whether there is a human face area in the video frame, and when a human face area is detected, then Send a signal to the beautification unit; the face detection library 2 is provided with a cascade classifier for pattern matching the video frame, which improves the detection accuracy and computing speed; the display unit 4 is used to display the processing results of the beautification unit 1; the beautification Unit 1 is connected to camera 2, face detection library 3 and display unit 4 respectively. Beautification unit 1 includes filter module 1-1, brightness module 1-2 and contrast module 1-3; filter module 1-1 receives fa...

Embodiment 2

[0044] Embodiment 2: as figure 2 As shown, the second object of the present invention is to provide a method for beautifying video applied to Internet video live broadcast, including:

[0045] ①. Initialization:

[0046] Set the radius r and threshold T of the fuzzy sampling area in the filtering module.

[0047] ②. The camera acquires the video frame I and transmits it to the beautification unit.

[0048] 3. The beautification unit calls the face detection library of OpenCV to detect the face area of ​​the video frame I.

[0049]The full name of OpenCV is OpenSourceComputerVisionLibrary. OpenCV is a cross-platform computer vision library based on (open source) distributions that can run on Linux, Windows and MacOS operating systems. OpenCV uses a face detection algorithm based on integrated machine learning originally proposed by Viola and Jones and improved by Rainer Lienhart. Based on haar-like features and Adaboost learning algorithm, the method classifies and trains...

Abstract

The invention discloses a video beautification system applied to Internet video live broadcast. The system comprises a beautification unit, a camera, a face detection library and a display unit. The beautification unit is connected to the camera, the face detection library and the display unit. The beautification unit comprises a filter module, a brightness module and a contrast module. The face detection library detects whether a face area appears in a video frame and emits a signal to the beautification unit when the face area is detected. The filter module receives the signal emitted by the face detection library and filtering the face area. The brightness module and the contrast module are connected to the filtering module and are used for adjusting the brightness and contrast of the video frame. According to the system and the method, the skin of the face can be effectively improved, the face feature of people is maintained, the details of other part of an image is completely maintained, the overall effect of the image is improved, thus the visual perception of human eyes is more natural and comfortable, the performance requirement of a computer is not high, and the system and the method can be realized in a PC and a mobile phone Android system.

Description

technical field [0001] The invention relates to the technical field of video imaging, in particular to a video beautification system and method applied to Internet video live broadcast. Background technique [0002] At present, there are many online entertainment platforms, and the anchors stay at home and do live video. The video taken by the camera is flat and clearly shows some unwelcome factors such as spots and wrinkles on the face. It is a strong request of anchors to eliminate unpopular factors and make the picture more beautiful. [0003] In the prior art, there is a face beautification method in real-time video, which beautifies the face in each frame of the video. The beautified current frame is used to replace the original current frame, and the above steps are continued for the next frame image of the current frame, so as to realize face beautification in the instant video. [0004] Because the method provided by the prior art has high requirements on the hard...
