Title
Click Carving: Interactive Object Segmentation in Images and Videos with Point Clicks
Abstract
We present a novel form of interactive object segmentation called Click Carving which enables accurate segmentation of objects in images and videos with only a few point clicks. Whereas conventional interactive pipelines take the user’s initialization as a starting point, we show the value in the system taking lead even in initialization. In particular, for a given image or a video frame, the system precomputes a ranked list of thousands of possible segmentation hypotheses (also referred to as object region proposals) using appearance and motion cues. Then, the user looks at the top ranked proposals, and clicks on the object boundary to carve away erroneous ones. This process iterates (typically 2–3 times), and each time the system revises the top ranked proposal set, until the user is satisfied with a resulting segmentation mask. In the case of images, this mask is considered as the final object segmentation. However in the case of videos, the object region proposals rely on motion as well, and the resulting segmentation mask in the first frame is further propagated across the video to obtain a complete spatio-temporal object tube. On six challenging image and video datasets, we provide extensive comparisons with both existing work and simpler alternative methods. In all, the proposed Click Carving approach strikes an excellent of accuracy and human effort. It outperforms all similarly fast methods, and is competitive or better than those requiring 2–12 times the effort.
