We propose a fast algorithm for automatically recognizing several common hand gestures and its application background is navigation of robot. The rapidity of this system reflects in four aspects: definition of gesture control signals, selection of gesture model, segmentation of hand gesture area, and features extraction. The experimental results show that the system can respond to gesture commands...
For roller fault diagnosis problems in textile spinning-frame, a method which combines an improved wavelet algorithm and support vector machine is presented. This method extracts feature information of the failure and classifies the failure. Based on the analysis of the frequency overlapping phenomenon encountered in traditional wavelet algorithm, the improved wavelet algorithm combines wavelet transform...
This paper presents a particle filter based solution to the problem of detecting large frozen lumps in an image sequence, taken of the feed to a crusher, which is used for size reduction of oilsand ore. In this application, the objects of interest, i.e., large frozen lumps, are characterized by a high level of image noise, irregular shapes, and uneven and variable surface texture. In addition, more...
