This paper examines the influence of head orientation in liptracking. There are two main conclusions: First, lip gesture analysis and head movement correction should be processed independently. Second, the measurement of articulatory parameters may be corrupted by head movement if it is performed directly at the pixel level. We thus propose an innovative technique of liptracking which relies on...

the present study was an attempt to assess religious orientation and life satisfaction as well as to find out relationship of religious orientation with life satisfaction among university students. university students were also compared on religious orientation and life satisfaction with respect to their gender. the data for the present study was obtained from university students [n=200 (males ...

Despite the fact that object oriented paradigm is actually widely adopted for software analysis, design, and implementation, there are still a large number of companies that continue to utilize the structured approach to develop software analysis and design. The fact is that the current worldwide agreement for object orientation is not supported by enough empirical evidence on advantages and di...

q-Ball imaging is a high-angular-resolution diffusion imaging technique that has been proven very successful in resolving multiple intravoxel fiber orientations in MR images. The standard computation of the orientation distribution function (the probability of diffusion in a given direction) from q-ball data uses linear radial projection, neglecting the change in the volume element along each d...

A new methodology to detect fibres orientation in composite materials, using image processing tools is introduced. Several examples with manufacturing defects are studied using RIMAPS technique and the Variogram method. The characterization is made from digitized images of the samples. Combined use of RIMAPS and Variogram analyses identified the orientation of fibres and determined the values o...

This paper focuses in explaining a Fourier based affine estimator which is applied to the task of Image Synthesis. An affine transformation is an important class of linear 2-D geometric transformations which maps variables into new by applying a linear combination of translation, rotation, scaling and/or shearing operations. Conventional retrieval systems are very effective when knowledge infor...

X-Ray Diffraction Contrast Tomography (DCT) is a recently developed, non-destructive synchrotron imaging technique which characterizes microstructure and grain orientation in polycrystalline materials in three dimensions (3D). By combining it with propagation based Phase Contrast Tomography (PCT) it is possible to get a full picture description for the analysis of local crack growth rate of sho...

It is well known that attention improves the visibility of a target. In this study, we examined the effect of attention on the selectivity profile for a target. We used a masking technique to measure the tuning function for detecting a target while cueing either its orientation or its location. In the presence of an orientation mask, uncued thresholds were maximally elevated with a parallel mas...
