In this paper we present a novel way of applying Zernike moments for image matching. Zernike moments are obtained from projecting image information under a circumscribed circle to Zernike basis function. However, the problem is that the power of discrimination may be reduced because hand images include lots of overlapped information due to their shape characteristic. On the other hand, in the pose...
In this paper we present a face orientation angle recognition system based on a modified Hausdorff distance. The Hausdorff distance determines the similarity between a given test image and a template. However, this operation is slow due to that the whole image is considered while using the original Hausdorff distance for matching. To address this matter we propose a divided Hausdorff distance which...
Dynamic time warping algorithm is a pattern matching algorithm that allows a nonlinear stretching of the data. In a recognition system using a matching algorithm, data clustering methods are used to reduce the number of gesture templates in the database, and thus reduce the computational cost; however, the recognition rate is degraded. In this paper, we proposed a DTW gesture recognition system that...
In this paper, a real time dynamic gesture recognition method based on a modified Levenshtein distance is proposed. The method addresses the issues faced in dynamic gesture recognition methods that are due to gesture variability within the class due to differences in the gesture speed. Since the gesture speed and duration will vary from one gesture to another, or from one person to the next, without...
