Figure-Ground Segmentation - Object Based

in Visual Analysis of Humans: Looking at People, Springer

Tracking with a moving camera is a challenging task due to the combined effects of scene activity and egomotion. As there is no longer a static image background from which moving objects can easily be distinguished, dedicated effort must be spent on detecting objects of interest in the input images and on determining their precise extent. In recent years, there has been considerable progress in the development of approaches that apply object detection and class-specific segmentation in order to facilitate tracking under such circumstances (“tracking-by-detection”). In this chapter, we will give an overview of the main concepts and techniques used in such tracking-by-detection systems. In detail, the chapter will present fundamental techniques and current state-of-the-art approaches for performing object detection, for obtaining detailed object segmentations from single images based on top–down and bottom–up cues, and for propagating this information over time.
