An Interactive Method of Image Feature Extraction Based on B_Splines Curves

An interactive method of image feature extraction based on B-Spline curves is proposed. B-Splines are piecewise polynomial curves that are guided by a sequence of points called the control points. The proposed method differs from traditional one in that the features of an image are extracted automatically according to a limited sequence of control points inserted by user in an interactive way, and the extracted image features are described as a series of B-Spline curves. Consequentially, the analysis of image features becomes easy and effective because of the specific properties of the B-Spline curves, and at the same time a significant data compression is achieved. An image feature extraction software package based on the proposed method has been realized in C language.
