Video summarization (VS) is one of key video signal processing techniques for unmanned aerial vehicles (UAVs). Essentially VS aims at eliminating redundant frames in aerial videos (AVs) with high similarity, which is helpful for quick browsing, retrieving and efficient storage without losing important information. For VS technique, how to measure the similarity between video frames is not a trivial...
Medical image segmentation plays an important role in digital medical research, therapy planning, and computer aided diagnosis. However, the existence of noise and low contrast make automatic liver segmentation remains an open challenge. In this work we focus on a novel variational semi-automatic liver segmentation method. First, we used the signed distance functions (SDF) representing pattern shapes...
