一种实时的自动抠图方法研究

图像的抠图是图像处理的一个基本问题,其本质是一个欠定的问题.目前流行的大部分抠图方法都需要用户进行交互操作,例如用户需提供三分图或者前背景的草图等.文中提出一种实时的自动抠图的方法,首先输入左右两幅图像,利用实时立体视觉方法生成深度图.接着根据深度图,通过阈值分割,得到比较粗糙的三分图.再利用粗糙的三分图来指导闭合形式...

Research on a Real-Time Automatic Image Matting

Image matting is a fundamental problem in image processing and is,in essence,an ill-posed problem.Most state-of-the-art algorithms require user interactions(such as the supply of trimaps or scribbles) to generate high-quality output.The authors of this paper propose a real-time automatic image matting method,which uses the input left and right images to generate a depth map through real-time stereo vision.Then,based on the depth map,a rough trimap is obtained by threshold segmentation.Finally,this rough tri...
