Most of current 3D face reconstruction methods based on 2D image are complex. In this paper, a novel and efficient method on the basis of geometric transformation is presented. The method is composed of two aspects, pose estimation and 3D model reconstruction. For the first part, an improved Active Shape Model(ASM) algorithm is used to detect the feature points of the face in the image, and the frontal...
Human age estimation based on face images can figure in a wide variety of real-world applications. In this paper, we propose a novel and efficient facial age estimation algorithm which decides human age in a hierarchical framework. Biologically, human lives can be roughly divided into two stages, the period from birth to adulthood and the period from adulthood to old age, which are quite different...
The aim of the paper is to show that localization of observed moving objects is possible in a multi-camera multimodal environment. The proposed method based on the simple foreground mask and there is no need for further pre-processing steps. The geometrical information for multiview localization also computed by using the statistical evaluation of foreground mask: homography, vertical vanishing point...
In this paper we use humans and chimpanzees brain MRI databases to develop methods for evaluating global brain asymmetries. We perform brain segmentation and hemispheric surface extraction on both populations. The human brain segmentation pipeline is adapted to chimpanzees in order to obtain results of good quality. To alleviate the problems due to cortical variability we propose a mesh processing...
The Aging process is a non-reversible process, causing human face characteristics to change over time as hair whitening, muscles drop and wrinkles. Recently, age estimation from facial images has emerged as a prominent research area. One of the most successful works is based on biologically inspired features (BIF). In this paper we extend BIF by incorporating fine detailed facial features, automatic...
In this paper, a novel human articulated pose estimation method based on AdaBoost algorithm is presented. The human articulated pose is estimated by locating major human joint positions. We learn the classifiers on a normalized image for classifying each pixel position into a certain category. Two different kinds of classifiers, bottom-up joint position classifier and top-down skeleton classifier,...
The knowledge about the body orientation of humans can improve speed and performance of many service components of a smart-room. Since many of such components run in parallel, an estimator to acquire this knowledge needs a very low computational complexity. In this paper we address these two points with a fast and efficient algorithm using the smart-room's multiple camera output. The estimation is...
Understanding and modeling of aging in human faces is an important problem in many real-world applications such as biometrics, authentication, and synthesis. In this paper, we consider the role of geometric attributes of faces, as described by a set of landmark points on the face, in age perception. Towards this end, we show that the space of landmarks can be interpreted as a Grassmann manifold. Then...
In this paper, we propose age and gender estimation system by vairous features. Age and gender has a lot of characteristics. These characteristics are one of the difficult cognitive process in human interaction. If we can extract the important feature of this cognitive process, it is considered that the age and gender estimation by the machine becomes possible. Therefore, we propose a method of age...
Although there have been a lot of studies on human detection in recent years, most of them have some particular requirements. However, some videos may have complicated scenes with low resolution and include both moving and standing people. The paper aims for individual detection under the challenging situation. An EM (expectation-maximum) based method has been developed to detect individuals in a...

Automatic people detection and tracking is a very essential task of video surveillance systems. It can improve a system's performance in important fields such as security, safety, human activity monitoring etc. In this paper we present a novel approach for people detection and 3D tracking. Our method is based on a human upper body 3D model and a likelihood function to evaluate its presence in a certain...
Tracking and counting multiple humans in complex situations is challenging. The difficulties are tackled with appropriate knowledge in the form of various models in our approach. Human motion is decomposed into its global motion and limb motion. Multiple human objects were segmented and their global motions were tracked in 3D using ellipsoid human shape models. An improved method aiming to estimate...
