Many recent superpixel algorithms for video content rely on dense optical flow vectors to propagate segmentation results from one frame to the next. In this paper, we assess the impact of the optical flow quality on the over-segmentation quality. Our evaluation shows that it is indispensable for videos with large object displacement and camera motion. But due to the high computational costs high-quality,...
Current Moving Object Detectors in airborne Region of Interest (ROI) coding systems for police surveillance applications used on-board of UAVs are often based on Global Motion Estimation (GME) techniques. Since in these scenarios the camera is moving, simple background removal approaches cannot be applied without a Global Motion Compensation (GMC). Common GMC algorithms assume the ground to be planar,...
