A novel elastic graph matching procedure based on multiscale morphological operations, the so called morphological dynamic link architecture, is developed for frontal face authentication. Fast algorithms for implementing mathematical morphology operations are presented. Feature selection by employing linear projection algorithms is proposed. Discriminatory power coeecients that weigh the matchi...

The frontal cortex might play an important role in the fear network, and white matter (WM) integrity could be related to the pathophysiology of panic disorder (PD). A few studies have investigated alterations of WM integrity in PD. The aim of this study was to determine frontal WM integrity differences between patients with PD without comorbid conditions and healthy control (HC) subjects by usi...

We address the pose mismatch problem which can occur in face verification systems that have only a single (frontal) face image available for training. In the framework of a Bayesian classifier based on mixtures of gaussians, the problem is tackled through extending each frontal face model with artificially synthesized models for non-frontal views. The synthesis methods are based on several impl...

A personal identiication system based on the analysis of frontal or proole images of the face has applications in human-computer interfaces, access control , surveillance etc. Among many practical face recognition schemes, image based approaches are possibly the most promising ones. However, the 2D im-ages/patterns of 3D face objects can change dramatically due to lighting and viewing variation...

We address the problem of estimating a person’s body height from a single uncalibrated image. The novelty of our work lies in that we handle two difficult cases not previously addressed in the literature: (i) the image contains no reference length in the background scene, (ii) the image contains the upper body only. In a nutshell, our method combines well-known ideas from projective geometry an...

adenoid cystic carcinoma (adcc) is a malignant neoplasm, which accounts for 5-10% of all salivary gland tumors (1). about 50% of these tumors originate from intraoral minor salivary glands usually in the hard palate (1). three clinically obvious characteristics of adcc include slow growth rate, perineural invasion and high incidence of distant metastasis (1). the most commonly-affected sites of...

purpose : to report an unusual case of dermoid cyst of the frontal bone case report : we report a case of 28-year-old man with a history of painless progressive proptosis of the left eye. ct-scan was showed a hypodense lesion that mainly located within the frontal bone with only a small intraorbital involvement. excisional biopsy was performed and histopathologic examination was compatible with...

Previous research showed that viewing symmetrically distorted faces for a few minutes causes undistorted faces to appear distorted in the opposite manner (face-distortion aftereffect, FDAE). Three experiments with 90 observers demonstrated that adaptation to an asymmetrically distorted face also causes FDAE, but does not affect perception of its mirror image. The results suggested the FDAE occu...

This paper presents an algorithm which detects automatically the feature points in a face image. This is a fundamental task in many applications, in particular in an automatic face recognition system. Starting from a frontal face image with a plain background we have effected an image segmentation to detect the different facial components (eyebrow, eyes, nose, mouth and chin). After this we hav...

We present a method for Shape-from-Texture in one of its most general forms. Previous Shape-from-Texture papers assume that the texture is constrained by one or more of the following properties: homogeneity, isotropy, stationarity, or viewed orthographically. We make none of these assumptions. We do not presume that the frontal texture is known a priori, or from a known set, or even present in ...
