Human faces detection method using genetic algorithm

A novel method to detect human facial regions from an image with a complex background has been proposed. To detect human facial regions precisely without imposing any constraints on face size, positions and any features such as glasses, beard and so on, the method employs Genetic Algorithm (GA). First, proposed method detects edges from an input image. Second, it searches ellipse regions using GA based on the idea that human faces can be approximated by ellipsoid. Finally, it judges whether the region is a human face or not one by one. We confirmed by computer simulations that the proposed method could detect human facial regions from various images.
