Following a brief overview of two-dimensional (2-D) parametric motion models commonly used in video manipulation and compression, we introduce trifocal transfer, which is an image-based scene representation used in computer vision, as a motion compensation method that uses three frames at a time to implicitly capture camera/scene motion and scene depth. Trifocal transfer requires a trifocal ten...

The problem of structure detection in images involves the identification of local groups of pixels that are both homogeneous and dissimilar to all nearby areas. Homogeneity can be measured with respect to any criteria of interest, such as color, texture, motion, or depth. No prior knowledge is assumed regarding the number of structures, their size or shape, or the degree of homogeneity that the...

this study has been done with the aim of determining the effect of financial and nonfinancial compensation satisfaction on employee engagement considering mediator role of perceived organizational justice. the research statistical population included eight hundred sixty two isfahan municipality employees. three hundred fourtheen persons were selected as the research sample by stratified random ...

Regional geologic mapping and gravity data reveal a variety of characteristics that must be accounted for in models for the formation and evolution of Western Ishtar Terra and Lakshmi Planurn, including: 1) high elevation, 2) plateau-shaped profile, 3) abnormally steep bounding slopes, 4) foredeeps, 5) polygonal outline, 6) adjacent orogenic belts, 7) volcanic plains, 8) plains emplaced synchro...

Cenozoic carbon dioxide, weathering, and calcite compensation depth reconciled in a comprehensive cycle model.

Block-based disparity compensation is an eÆcient prediction scheme for encoding multi-view image data. Available scene geometry can be used to further enhance prediction accuracy. In this paper, three di erent strategies are compared that combine prediction based on depth maps and 3-D geometry. Three real-world image sets are used to examine prediction performance for di erent coding scenarios....
