基于Kinect的人物抠图算法

The study of Kinect figures matting algorithm

针对传统抠图过程中要求一定的背景颜色、较好的光线、人机交互繁琐、不具备实时性等问题,提出以Kinect为硬件基础的基于用户索引识别信息(简称用户ID)和识别人物的抠图算法并进行仿真,实现了人物的自然实时抠图效果.整个抠图过程简单方便,不需除Kinect和电脑以外的任意设备,抠图效果稳定,在较暗的环境中也能进行抠图工作,并且具有实时性.

The figure algorithm by using Kinect was proposed to solve the problems in tradi- tional matting process, such as a certain background color required, better light, cumbersome Human-computer interaction, non real time and so on. The matting algorithm based on user ID and figure idontfication realized the figures＇ natural real-time matting through simulation. It is achieved easily in the entire matting process and no equipments are needed in addition to a Ki- nect and a computer. It has stable matting effect, real-time features, and the matting can be done in darker environments.
