A method for face parametrical statistical features extraction from intensity fragments and segments is considered. Pixel coordinates means are calculated. An algorithm for face classification is proposed. Illustration of features and classification process for given features are presented.
Face recognition has certain impediments due to alignment, illumination, facial expressions. Several techniques have been proposed to rectify these challenges. In recent years, many researchers have addressed challenges due to ageing, plastic surgery, twin identification, make-up and hairstyle. But, the impact of weight variation on face recognition has not been explored much. In contrary to other...
Estimating eye centers is an important computer vision problem with several applications. In the past, eye center localization was constrained by the use of special hardware such as infrared cameras. Methods that estimate eye centers based on visible light have also been suggested in the literature, but these methods are inaccurate when used with low resolution images and wide ranges of lighting....
Facial hair detection and segmentation play an important role in forensic facial analysis. In this paper, we propose a fast, robust, fully automatic and self-training system for beard/moustache detection and segmentation in challenging facial images. In order to overcome the limitations of illumination, facial hair color and near-clear shaving, our facial hair detection self-learns a transformation...
This paper describes an illumination normalization technique which works at the pre-processing stage where the face image is first divided into equal sub-regions. Each sub-region is then processed separately for illumination normalization. Then the segments are joined back followed by further processing like noise removal and contrast enhancement. The proposed technique is tested on Yale dataset and...
When it is necessary to analyze a personpsilas face, whether it is for recognizing pathologies, emotions, or states of mind, it becomes necessary to obtain a maximum of information of the facial characteristics that especially reflect these aspects. These characteristics are principally, the mouth, eyes and eyebrows. The start of the analytic process, once the face and the facial feature to be analyzed...
