This paper proposes a computer-aided cirrhosis diagnosis system to diagnose cirrhosis based on ultrasound images. We first propose a method to extract a liver capsule on an ultrasound image, then, based on the extracted liver capsule, we fine-tune a deep convolutional neural network (CNN) model to extract features from the image patches cropped around the(More)
Android occupies the absolute dominant position in mobile operating system and has the largest market share. Meanwhile, Android faces the risk of malicious insiders leaking sensitive information. In this paper, we present DefDroid, a repackaging tool for enforcing security policies by modifying Android applications without root privilege. The main(More)
Automatically and reliably tracking numerous flying objects in 3D space is of great significance for not only scientific researches such as collective behavior analysis, but also practical applications such as designing multi-agent robots. However, it remains a challenging task due to the large population, similar appearance, and severe occlusion happening(More)
Fish tracking is an important step for video based analysis of fish behavior. Due to severe body deformation and mutual occlusion of multiple swimming fish, accurate and robust fish tracking from video image sequence is a highly challenging problem. The current tracking methods based on motion information are not accurate and robust enough to track the(More)
