نویسندگان
چکیده
Face detection is a crucial step in many vision applica-tions. Since the Viola and Jones face detector, many feature extraction approches based Adaboost are proposed.This paper presents a novel approach to extract effective features for face detection system. Both LBP and three Patch LBP (TPLBP) with joint integral histogram are used to extract features. The joint integral histogram was firstly proposed for stereo matching application. Its effectiveness has

LDA based Reduced Joint Integral Histogram for Feature Extraction Case of study: Face Detection
The face pattern is described by extracted features using the new Reduced Joint Integral Histogram (RJIH) data structure. Extending the classical representations of integral images and integral histograms, it joins the global information of two images. Then, we turn to Linear Discriminant Analysis (LDA) to project the obtained Joint Integral Histogram from d−dimensional subspace to one dimensio...
متن کاملAdaboost face detector based on Joint Integral Histogram and Genetic Algorithms for feature extraction process
Recently, many classes of objects can be efficiently detected by the way of machine learning techniques. In practice, boosting techniques are among the most widely used machine learning for various reasons. This is mainly due to low false positive rate of the cascade structure offering the possibility to be trained by different classes of object. However, it is especially used for face detectio...
متن کاملHistogram Features-Based Fisher Linear Discriminant for Face Detection
The face pattern is described by pairs of template-based histogram and Fisher projection orientation under the paradigm of AdaBoost learning in this paper. We assume that a set of templates are available first. To avoid making strong assumptions about distributional structure while still retaining good properties for estimation, the classical statistical model, histogram, is used to summarize t...
متن کاملBoosted Gaussian Classifier with Integral Histogram for Face Detection
Novel features and weak classifiers are proposed for face detection within the AdaBoost learning framework. Features are histograms computed from a set of spatial templates in filtered images. The filter banks consist of Intensity, Laplacian of Gaussian (Difference of Gaussians), and Gabor filters, aiming at capturing spatial and frequency properties of faces at different scales and orientation...
متن کاملSimple and Fast Face Detection System Based on Edges
Face detection is an important first step to many advanced computer vision, biometrics recognition and multimedia applications, such as face tracking, face recognition, and video surveillance. In this paper, a faster face detection system is proposed with minimal features based on edges. Our proposed framework consists of three steps: initially the images are enhanced by applying median filter ...
