This paper presents image-based rendering related techniques; (1)a computer vision technique to estimate accurate epipolar geometry and (2) a n image coding technique to compress multiple-viewpoint images, which are stored for reconstruction of any arbitrary view of 3-0 object, with the epipolar geometry. Uhlike other epipolar geometry estimation techniques based o n the correct sets of feature...

Subclinical hyperthyroidism is known to be associated with the risk of fractures in elderly people. However, there are few studies assessing whether low normal thyroid-stimulating hormone (TSH) levels affect bone density and geometry. Here, we aimed to assess the influence of the TSH level on bone mineral density (BMD) and geometry in elderly euthyroid subjects. This was a cross-sectional cohor...

Minimum storage regenerating codes have minimum storage of data in each node and therefore are maximal distance separable (MDS for short) codes. Thus, the number of nodes is upper bounded by 2, where b is the bits of data stored in each node. From both theoretical and practical points of view (see the details in Section 1), it is natural to consider regenerating codes that nearly have minimum s...

negotiations among nations on policies to promote international economic integration have widened in recent years to cover new issues; for example, foreign direct investment rules, policies to promote competition, the international movement of labor, the environment and monetary :union:. in these negotiations, a consensus among the parties negotiating is usually lacking and many of these negoti...

recently many studies have been done on different issues of using multiple antennas at transmit and receive sides of a radar system in a mimo (multiple input multiple output) configuration. in addition, for the electronic warfare‟s purposes, the utilization of available signals of the environment to detect the targets has gained considerable attention in recent years. such passive radars use th...

In order to explore measuring accuracy of coded-structured-light 3D measurement system onto high reflectance surface of turbine blade, measuring error analysis, system parameter design and uncertainty evaluation were investigated. First, device parameters and azimuth parameters of analytic geometry model and projective geometry model of coded structured light system were analyzed and unified. S...

This study addresses intelligent techniques for fulfilling quality control of bead-on-plate welding. A new visual double-sided sensing system capable of imaging the weld pool topside and backside simultaneously in a frame was provided to determine the weld pool geometry parameters. The imaging principle was analyzed with spectrum distribution, in which the weld pool was illuminated by arc light...

Absfruct We construct a class of codes derived from algebraic plane curves. The concepts and results from algebraic geometry we use are explained in detail, and no further knowledge of algebraic geometry is needed. Parameters, generator and parity-check matrices are given. The main result is a decoding algorithm which turns out to be a generalization of the Peterson algorithm for decoding BCH c...
