In this paper we present a face detection algorithm for color images with complex background. We include color information into a face detection approach based on principal components analysis (PCA). A skin color probability image is generated by doing a color analysis and the PCA is performed on this new image instead of the luminance image. Experiments show that color information improves the...

Since all faces share the same first-order configuration, individual faces are recognized by subtle differences in their individual features and second-order configuration. This study asked two questions about the ERP signatures of featural and configural face processing. First, which ERP components are sensitive to subtle modifications of features and second-order configuration? Secondly, does...

In this work we propose a new method of 3D face computational photography based on a facial expressions training dataset composed of both facial range images (3D geometry) and facial texture (2D photo). The method allows to obtain a 3D representation of facial geometry given only a 2D photo and a set of facial landmarks, which undergoes a series of transformations through the estimated texture ...

Face recognition from images is a sub-area of the general object recognition problem. It is of particular interest in a wide variety of applications. Here, the face recognition is based on the new proposed modified PCA algorithm by using some components of the LDA algorithm of the face recognition. The proposed algorithm is based on the measure of the principal components of the faces and also ...

Methods for face recognition which are based on face structure are among techniques without supervision and produce unfavorable results in the presence of linear changes in images. PCA is a linear transform and a powerful tool for data analysis but does not produce good results for face recognition when there are non-linear changes resulting from changes in position, intensity and gesture in th...

Face is a popular topic of research in computer vision, image analysis and understanding. This paper proposes a method to detect straight posed face as well as tilted face in colour images. Algorithm first detects skin colour region and then skin region is further processed by finding connected components and holes. Each connected components is tested to extract facial features and Y-value of e...

With the development of information technology, face recognition technology has been continuously developed. This technology has attracted the attention of many researchers, including institutions and production enterprises. Face recognition technology has become a relatively independent application technology area in various social services. This paper presents a face recognition algorithm bas...
