Abstract:
1. A method for extracting and matching gesture features of an image, comprising the steps of: (A) capturing an input gesture image; (B) determining a closed curve formed by a binary contour image of the gesture image by preprocessing the gesture image; (C) drawing a curvature scale space (CSS) image of the gesture image based on the closed curve; (D) determining feature parameters of a plurality of sets of the gesture image by extracting first plural peaks from the CSS image as basis points, wherein each peak is a local maximum larger than a critical value and each feature parameter of the sets of the gesture image is obtained by performing the steps of: (E) comparing each feature parameter obtained in step (d) of the sets of the gesture image with each feature parameter of a plurality of reference gesture shapes for determining a gesture shape corresponding to the gesture image.
