报告题目:Automatic Portrait Segmentation and Matting

主持人:王乃岩(TuSimple


报告摘要In this talk, I will introduce our fully automatic segmentation and matting methods for portrait images. The method does not need any user interaction, which was however essential in most previous approaches. In order to accomplish this goal, a new end-to-end convolutional neural network (CNN) is proposed taking the input of a portrait image. It outputs the segmentation or mating results. Our CNN considers not only image semantic prediction but also pixel-level matte optimization. In addition, a new portrait image dataset is constructed with our labeled segmentation and matting ground truth. Our automatic method achieves comparable segmentation and matting results with state-of-the-art methods that require specified foreground and background regions or pixels. Many applications are enabled given the automatic nature of our system.
