ABSTRACT:
In a method for reconstructing a lip contour signal (LCS) having edge points (EP's) representing the position and shape of a lip image being symmetrical, a reconstructed LCS is obtained based on the LCS by using a standard lip contour signal (SLCS) having predetermined standard edge points (SEP's), the SLCS representing the position and shape of a standard lip image being symmetrical. In detail, the center point of the LCS is first matched as an origin of a two dimensional xy-plane with the center point of the SLCS. And then the coordinates of the N number of EP's of the LCS are corrected to generate a corrected LCS having N number of corrected EP's by stretching the x-coordinates of the N number of EP's in accordance with a predetermined stretching rule under the condition that a horizontal left end EP (HLEP) and a horizontal right end EP (HREP) of the corrected LCS coincide with a horizontal left end SEP (HLSEP) and a horizontal right end SEP (HRSEP) of the SLCS, respectively, wherein the x-coordinate of the HRSEP is greater than that, of the HREP on the xy-plane. Thereafter, N number of reconstructed edge points (REP's) are obtained based on the N number of corrected EP's of the corrected LCS and the N number of SEP's of the SLCS, thereby generating a reconstructed LCS having the N number of REP's.
