图像与视频提取技术综述

A survey on technology of image and video matting

近年来,图像与视频提取技术逐渐成为图像处理领域的研究热点,也是机器视觉、模糊识别等系统开发中的关键技术之一。本文回顾了图像与视频提取技术的发展过程,并归纳了其主要的研究方向。在总结图像与视频提取领域中重要研究活动的基础上,提出了图像与视频提取的两大研究思路,给出相关的评估标准。探讨现有研究的不足之处及其原因,并提出解决方案构想。最后,展望图像与视频提取技术的发展前景和面临的挑战。

Recently, the technology of image and video matting （IVM） is emerging as one of the primary research subjects in the image processing areas and the key technologies for the development of Machine Vision and Fuzzy Recognition. In this paper, the history and major direction of IVM are summarized, and a general model of IVM is as well brought up after analyzing and comparing several classical definitions about IVM. Based on summing up the activities about IVM, two categories of study about IVM are extracted out, and evaluating criterions of IVM are subsequently introduced. In addition, this paper discusses some research deficiency on IVM and explains the causes simultaneously, then proposes a conceiving scheme. Finally, it is concluded with some significant promising tendencies and confronting challenges in the field of IVM.
