IMAGE SEGMENTATION METHOD BASED ON GDT(GEODESIC DISTANCE TRANSFORM), AND AN IMAGE ELIMINATION METHOD OF FACE AUTHENTICATION SYSTEM USING THE SAME, PARTICULARLY USING LINEAR COMBINATION FOR RESULTS
PURPOSE: An image segmentation method based on GDT(Geodesic Distance Transform), and an image elimination method of face authentication system using the same are provided to acquire accurate results by using a linear combination for plural results and enabling a high speed operation resulting from the parallel processing for various algorithms.;CONSTITUTION: An initial point for an image inputted to an image recognition system is determined(S200). The image is classified by using a water shed algorithm and the algorithms which adopt a GDT(Geodesic Distance Transform) and a Gaussian mixing model, wherein each algorithm is respectively processed in parallel(S300,S400,S500). A weight value is applied to a result value obtained through the algorithms. The weight values to which the weight value is applied are linearly combined(S600).;COPYRIGHT KIPO 2011
