Research on word sense disambiguation (WSD) is of great importance in natural language processing fields. In this paper, a novel word sense disambiguation system is designed in which bayesian theory is applied to determine correct sense of an ambiguous word. Morphology knowledge in word unit is mined to guide WSD process. Neighboring morphology knowledge of an ambiguous word is used as feature for...
A machine vision system for special shaped softgel inspection is proposed in this paper, which is composed of a pair of CMOS cameras and a diffuse blue illuminator. Because the flaws appear in softgel shells edge is difficult to detect, these two cameras are arranged symmetrically upon softgels with a certain angle to avoid blind area. An image segment method combined automatic threshold and edge...
Traditional barcode recognition algorithm usually do not fit the cylindrical code but the one on flat surface. This paper proposes a low-cost approach to implement recognition of the curved QR codes printed on bottles or cans. Finder patterns are extracted from detecting module width proportion and corners of contours and an efficient direct least-square ellipse fitting method is employed to extract...
In recent years, facial expression recognition has attracted a lot of attention because of its importance in human-computer interaction. However, most previous work has focus on posed expression. In this paper, we propose a spontaneous facial expression recognition method based on feature point tracking. First, all expression sequences are normalized according to their pupils' coordinates. Second,...
