Color Correction for Face Detection Based on Human Visual Perception Metaphor
نویسنده
چکیده
In this paper we present a method of automatic color correction of face images and its application in a face detection algorithm. The color correction method is based on the phenomenon of color constancy observed in human visual perception. This technique is further applied in a face detection system, which draws upon the analogy to the parallel organization of visual neural pathways, the magnoand parvocellular channels. Presented method proved to be efficient in diverse background and illumination conditions, including face images with background chromatically close to human skin and where prominent facial features are obscured by adverse illumination conditions.

The human facial recognition is the base for all facial processing systems. In this work a basicmethod is presented for the reduction of detection time in fixed image with different color levels.The proposed method is the simplest approach in face spatial localization, since it doesn’trequire the dynamics of images and information of the color of skin in image background. Inaddition, to do face...
متن کاملReduced-Reference Image Quality Assessment based on saliency region extraction
In this paper, a novel saliency theory based RR-IQA metric is introduced. As the human visual system is sensitive to the salient region, evaluating the image quality based on the salient region could increase the accuracy of the algorithm. In order to extract the salient regions, we use blob decomposition (BD) tool as a texture component descriptor. A new method for blob decomposition is propos...

Visual saliency is a cognitive psychology concept that makes some stimuli of a scene stand out relative to their neighbors and attract our attention. Computing visual saliency is a topic of recent interest. Here, we propose a graph-based method for saliency detection, which contains three stages: pre-processing, initial saliency detection and final saliency detection. The initial saliency map i...
متن کاملHuman Skin Color Modeling, Segmentation and Correction for Face Detection
Human skin segmentation in colored images is closely related to face detection and face recognition systems as a preliminary critical required step where it is necessary to search for the precise face location. An important challenge for any image segmentation approach is to accommodate varying illumination conditions and different ethnic groups. We present a general approach for modeling, segm...
