Research And Implementation Of Facial Beautification Based On Video

With the rapid development of mobile Internet,mobile phone as the most widely used mobile information terminal,occupies a very important position in mobile Internet.At present,as a new social mode of live broadcasting,it is becoming an important way for people to enjoy entertainment at home and abroad under the lightning speed.One of the most basic functions in the live broadcast software is facial beauty.However,at present,the beauty function provided by most live broadcast software still cannot meet user's requirements.Therefore,the video beautification technology still has a lot of room for development and improvement.In this paper,we implement a video virtual beauty.We first implement face detection and facial feature alignment by using a Convolutional Neural Networks(CNN).Then,using the image fusion and smoothing technology to achieve face beauty.The main work of this paper is as follows:(1)Analysis of the existing face alignment,single-person virtual cosmetics,video virtual cosmetics and other related technologies,provide technical foundation and corresponding solutions for video virtual beauty system.This paper mainly studies some representative methods of face alignment and beautification.Face alignment is mainly based on regression and optimization methods.Beauty is mainly about facial geometry,skin color beautification and beautification of makeup.(2)In the aspect of face alignment,this paper studies some face alignment models by using some advanced theories and methods in image processing and computer vision.According to the research results,this paper applies a more accurate face alignment algorithm.The algorithm is using the MDM learning framework to achieve face alignment.With the rotation of the face,facial features also make the corresponding changes.(3)In terms of virtual beauty,according to the detected facial areas and facial alignment,this paper achieves virtual beauty makeup by the fusion,and integrates the cartoon decorative images into the corresponding regions of the head.At the same time,to achieve facial skin beauty by using image smoothing,make skin more natural and beautiful.Video virtual beauty in the academic field has great research value,while in real life has broad application prospects.This article's video virtual beauty has great practical value.
