Detection of Pose and Scale Variant Human Faces in Color and Gray Images

Chang-Woo Park, Taegun Lee, Young-Ouk Kim and Ha-Gyeong Sung

Abstract:
This study present an effective method of face and facial feature detection under pose variation of user face in complex background. The approach is a flexible method that can be performed in both color and gray facial image and is also feasible for detecting facial features in quasi real-time. Based on the characteristics of the intensity of neighborhood area of facial features, new directional template for facial feature is defined. From applying this template to input facial image, novel Edge-like Blob Map (EBM) with multiple strength intensity is constructed. Regardless of color information of input image, using this map and conditions for facial characteristics, it is shown that the locations of face and its features-i.e., two eyes and a mouth-can be successfully estimated. Without the information of facial area boundary, final candidate face region is determined by both obtained locations of facial features and weighted correlation values with standard facial templates. Experimental results from many color images and well-known gray level face database images authorize the usefulness of proposed algorithm.
