In face authentication and other face biometric methods, an image of a person can be misclassified if the pose of their face is different than that of the training data unless there are steps taken to eliminate these inaccuracies. The methods in this paper are designed to improve the accuracy of a face authentication system when the pose between the input image and training images are different...

The 3D Morphable Model (3DMM) and the Structure from Motion (SfM) methods are widely used for 3D facial reconstruction from 2D single-view or multiple-view images. However, model-based methods suffer from disadvantages such as high computational costs and vulnerability to local minima and head pose variations. The SfM-based methods require multiple facial images in various poses. To overcome th...

IN CONGENITAL dextrocardia the problem is frequently whether dextroversion or a mirror-image dextrocardia is present. In the former the atria preserve their usual relationship in the frontal plane but the left ventricle lies anterior to the right. In mirror-image dextrocardia there is atrial inversion and the right ventricle lies anterior to the left. The electrocardiographic findings are gener...

In the past, researchers investigated silent lipreading in normal hearing subjects with functional neuroimaging tools and showed how the brain processes visual stimuli that are normally accompanied by an auditory counterpart. Previously, we showed activation differences between males and females in primary auditory cortex during silent lipreading, i.e. only the female group significantly activa...

OBJECTIVE To compare patients' goals in aesthetic rhinoplasty with aesthetic ideals by analyzing changes requested through computer imaging during the initial consultation. METHODS The frontal and lateral views of 20 consecutive female rhinoplasty patients were analyzed retrospectively before and after using image manipulation software. Indexes from the frontal view included the ratio of alar...

This paper introduces a novel methodology that combines the multi-resolution feature of the Gabor wavelet transformation (GWT) with the local interactions of the facial structures expressed through the Pseudo Hidden Markov model (PHMM). Unlike the traditional zigzag scanning method for feature extraction a continuous scanning method from top-left corner to right then top-down and right to left ...

BACKGROUND An extensive literature describes structural lesions in apraxia, but few studies have used functional neuroimaging. We used positron emission tomography (PET) to characterize relative cerebral glucose metabolism in a 65-year-old, right-handed woman with progressive decline in ability to manipulate objects, write, and articulate speech. OBJECTIVE To characterize functional brain org...

In this paper, a novel multi-pose face image recognizing method is presented. In this algorithm, the face with multi-pose can be recognized by comparing it with the eigenface which is generated from 3D face model database, view point of the 3D face model is estimated from the face image, the estimation algorithm utilize the facial geometrical feature to estimate head pose parameter which can be...

It is usually held that perceptual spatial stability, despite smooth pursuit eye movements, is accomplished by comparing a signal reflecting retinal image slip with an internal reference signal, encoding the eye movement. The important consequence of this concept is that our subjective percept of visual motion reflects the outcome of this comparison rather than retinal image slip. In an attempt...

We propose a person identi cation technique that can recognize and verify people from unconstrained video and audio. We do not expect fully frontal face image or clean speech as our input. Our recognition algorithm can detect and compensate for pose variation and changes in the auditory background and also select the most reliable video frame and audio clip to use for recognition. We also use 3...
