Abstract: A kind of description function and the initiation point of a closed curve are defined using the centroid and the shape-specific point of Aggarwal. Based on periodic Daubechies wavelet coefficients feature of the description function, the global matching problem and the local matching problem of the contour curve are discussed. To meet the needs of fast recognizing target and accurately distinguishing object, we propose a simple matching model and an accurate matching model for our method. Experiments indicate good stability and reliability of our method and they also show real time ability of fast wavelet algorithm used in the model.
