报告内容摘要:

In this talk, I will illustrate how to perform both real-time object tracking and semi-supervised video object segmentation with a single simple approach. The method, dubbed SiamMask, acts on the offline training procedure of popular fully-convolutional Siamese approaches for object tracking by augmenting their losses with a binary segmentation task. Once trained, SiamMask solely relies on a single bounding-box initialisation and operates online, producing class-agnostic object segmentation masks and rotated bounding boxes at 35 frames per second. Despite its simplicity, versatility and fast speed, our strategy allows us to establish a new state-of-the-art among real-time trackers on VOT-2018, while at the same time demonstrating competitive performance and the best speed for the semi-supervised video object segmentation task on DAVIS-2016 and DAVIS-2017.
