The Competitive Coding (CompCode) scheme, which extracts and codes the local dominant orientation as features, has been widely used in finger knuckle print (FKP) verification. However, CompCode may lose some valuable information such as multiple orientation and texture of the FKP image. To remedy this drawback, a novel multiple orientation and texture information integration scheme is proposed ...

extending the export of high technology-based products is one of the most important goals of long term strategy of the country’s export development. in the present study, the main structures influencing the success of exportation through intangible resources (market orientation and entrepreneurial orientation) and the role of dynamism of export target market are investigated by considering the ...

-An array of sigmoidal tension gashes from the Idaho-Wyoming thrust belt changes laterally into a continuous vein. Detailed mechanical twin analysis was used to determine the strain variation in the optically and chemically homogeneous blocky calcite filling. In the continuous portion of the vein complex, the shortening axes are parallel to the vein boundary. However, the orientation of the sho...

Essentially all Computer Vision strategies require initial computation of orientation structure or motion estimation. Although much work has been invested in this subfield, methods have so far been very computationally demanding and/or not very robust. In this paper we present a novel method for computation of orientation tensors for signals of any dimensionality. The method is based on local w...

In this paper, we propose a novel distributed formation control strategy, which is based on the measurements of relative position of neighbors, with global orientation estimation in 3-dimensional space. Since agents do not share a common reference frame, orientations of the local reference frame are not aligned with each other. Under the orientation estimation law, a rotation matrix that identi...

Many cross cultural studies have mentioned two distinct forms of thinking, holistic and analytic thought, and argued that one of the crucial differences between them is their attentional focus on focal object and its context. Furthermore, in face recognition studies, it has been replicated that face recognition is a configural process and is fostered by prior global processing orientation. The ...

Elements of a contour are often easier to detect when they possess collinearity, with their local orientations matching the global orientation of the contour. We recently reported attentional modulation of such lateral interactions between a central near-threshold target Gabor patch and flanking high-contrast patches (Freeman et al, 2001 Nature Neuroscience 4 1032-1036). Here, we examined wheth...

The extraction of shape from shading has a relatively long history within the field of computer vision. There have been two general classes of algorithm developed: Local algorithms, which attempt to estimate shape from local variations in image intensity, and information propagation algorithms, which attempt to propagate contour information across a shaded surface. Local algorithms, such as Pen...
