摘要:When thresholding is performed on images for isolating the facial area from the background, many defect areas (holes) remain in the facial area. The holes must be eliminated before extracting facial features, such as the eyes, mouth, and nose, which should be extracted with a high degree of accuracy. An algorithm that quickly eliminates holes instead of using conventional propagating and shrinking operations is described. The algorithm can be used independently of the size of the holes.
