Abstract
Face segmentation plays an important role in various applications such as human computer interaction, video surveillance, biometric systems, and face recognition for purposes including authentication and authorization. The accuracy of face classification system depends on the correctness of segmentation. Robustness of the face classification system is determined by the segmentation algorithm used, and the effectiveness in segmenting images of similar kind. This paper explains the level set based segmentation for human face images. The process is done in two stages: In order to get better accuracy, binarization of the image to be segmented is performed. Next, segmentation is applied on the image. Binarization is the process of setting pixel intensity values greater than some threshold value to "on" and the rest to "off". This process converts the input image into binary image which is used for segmentation. Second process is image segmentation for eliminating the background portion from the binarized image which is obtained after the binarization of the original image. Conventional approaches use separate methods for binarization and segmentation. In this paper we investigate the use of recently introduced convex optimization methods, selective local/global segmentation (SLGS) algorithm [16] for simultaneous binarization and segmentation. The approach is tested in MATLAB and satisfactory results were obtained.
