METHOD FOR DETECTING FACES FROM COLOR IMAGES

摘要

PURPOSE: A method for detecting faces from color images is provided to retrieve entire images of a face by selecting a face color region of a color image to retrieve the region only, and by using a retrieving window of the selected region as a face color region to detect a face. CONSTITUTION: Face regions are divided on the basis of colors of color images. Face regions are selected by a regular standard. The selected face regions are labelled. Regions which are not the face regions are eliminated on the basis of predetermined face region sizes. Convex shape regions and concave shape regions are detected on corresponding images of the face regions passing through filtering processes. Available face detecting regions are filtered by using a face retrieving window, to analyze distributions of the convex/the concave shape regions. A final face region is decided by using a size of the face detecting window for the available face detecting regions.
