碩士 === 華梵大學 === 資訊管理學系碩士班 === 100 === Hand tracking often use template matching, confirm to the correct of hand position that is in the image. We use edge orientation into both templates and image for six kinds of channel for compare. When we calculating orientation that will be affected, as about the result of edge detection. When appear deviation of pixel location, and then appear error in the edge orientation is possible. That exist some diversity between hand and templates, especially the articulation of hand and finger. Such error will be lead to failure of hand track even. We reference multi-valued logic concept in the fuzzy theory to expand orientation of channel and combine the simplify templates to solve the aforementioned problem improve the accuracy rate. Experimental design part of analyze edge orientation assignment and the simplify templates according to results the method can effectively improve the errors in complex scenes.
