Health problems of the elderly are more and more serious with the growth of aging population. The accidents like falling down need to be paid more attention especially. Through the analysis of the existing detection methods, a more simple and rapid algorithm about human body fall detection based on the Kinect sensor is proposed in this paper. This algorithm is composed of three parts, which are moving...
Hair plays an important role in human appearance. However, hair segmentation is still a challenging problem partially due to the lack of an effective model to handle its arbitrary shape variations. In this paper, we present a part-based model robust to hair shape and environment variations. The key idea of our method is to identify local parts by promoting the effectiveness of the part-based model...
Hair is an important aspect of human appearance. Hair color has been employed to facilitate face retrieval in literature, but hair style is still dismissed because of the challenges of its segmentation. In this paper, we propose a novel hair style retrieval algorithm in unconstrained environments. In contrary to defining similarity based on features, we base our measurement directly on hair shapes...
Clothing is one of the most informative cues of human appearance. In this paper, we propose a novel multi-person clothing segmentation algorithm for highly occluded images. The key idea is combining blocking models to address the person-wise occlusions. In contrary to the traditional layered model that tries to solve the full layer ranking problem, the proposed blocking model partitions the problem...
A new method is proposed to overcome illumination intensity difference influences the recognition result which occurs during collecting session in this paper. The problem is not effective solved in original algorithm. This algorithm proposes to match after moving two matching feature surfaces to one equivalence gray plane. It also uses the theory of gray surface matching based on feature analysis...
In this paper, a real time computer vision system was developed to detect a glass bottle filled with transfusion solution on a packing line. The theory, the mechanical structure, and the detection algorithm are described. Foreign substances mixed in transfusion solution are distinguished from bottle side wall defects by a relative movement between a resting bottle and the inside moving solution. Foreign...
