Geometrical Modeling of leaf Shape Based on Image Processing and Feature Points Detection

A method of establishing the geometrical model of leaf shape is used. The method starts with the binarization and edge detection of the digital image. According to the topology of the pixels in the edge, a linked list of Coordinates is created by the scanning algorithm. With the feature points detected from the linked list, the geometrical model of leaf shape is upbuilt by the rational cubic spline interpolation. Some experiment results show that this method is more simple and convenient and needs less data.
