Real-time human tracking in complex environments usually presents many challenges, such as partial/complete occlusions caused by irregular motion and similar-color distractors. Switching Linear Dynamic System(SLDS) and Meanshift(MS) are two successful approaches, although both have inherent deficiencies, like accumulated prediction and correction errors in(More)
Image saliency detection has attracted much attention in recent years, while several challenging problems are still unsolved, such as inaccurate saliency detection in complex scenes and suppressing salient objects near image borders. In this paper, a novel algorithm is proposed to solve these problems. Firstly, we collect background seeds from image borders(More)
To better understand the expression of human smile, there have been considerable studies about automatic smile detection. Despite all the research, few attention is paid to analyse a smile in a comprehensive way. In this paper, a smile analysis system is presented to detailedly measure a person’s smile, which consists of three main modules: smile detection,(More)
