Feasibility of tomography with unknown view angles
Proceedings 1998 International Conference on Image Processing. ICIP98 (Cat. No.98CB36269), 2000In the standard two-dimensional (2-D) parallel beam tomographic formulation, it is generally assumed that the angles at which the projections were acquired are known. We have previously demonstrated, however, that under fairly mild conditions these view angles can be uniquely recovered from the projections themselves.

Estimating viewing angles in mobile street view search
2012 19th IEEE International Conference on Image Processing, 2012Recent years have witnessed an exciting progress in mobile visual search with applications to location recognition and streaming augmented reality. Most existing works among them are deployed with reference images coming from street views in urban scene. In such scenario, an interesting yet untouched problem is how to determine the viewing angle of the

Oblique angled view for coracoid fractures
Skeletal Radiology, 1983In cases of shoulder injury when clinical signs suggest a possible coracoid fracture, a 20 degree posterior oblique film with 20 degrees of cephalad angulation has been shown to demonstrate coracoid fractures when other views have been inconclusive.

Uniqueness of tomography with unknown view angles
IEEE Transactions on Image Processing, 2000In the standard two-dimensional (2-D) parallel beam tomographic formulation, it is assumed that the angles at which the projections were acquired are known. In certain situations, however, these angles are known only approximately (as in the case of magnetic resonance imaging (MRI) of a moving patient), or are completely unknown. The latter occurs in a

Wide-angle viewing lens for vitrectomy
American Journal of Ophthalmology, 2004To report a new wide-angle viewing contact lens for vitrectomy.New surgical instrument.The new wide-angle viewing lens is made of glass and polymethyl methacrylate without a plastic rim. The diameter is reduced to 16.2 mm. In addition to a smaller diameter than the currently available lens, the new lens is partially cut to reduce the lens diameter.A ...

Viewing angle analysis for wide-viewing angle multi-layer integral imaging display
2009 Conference on Lasers & Electro Optics & The Pacific Rim Conference on Lasers and Electro-Optics, 2009We describe a viewing angle of wide-viewing multi-layered integral imaging display. The viewing angle is dependent on the position of the integrated image point.

A wide-angle viewing system offers a panoramic view of the surgical field and also improves the safety and efficacy of the vitreoretinal surgical procedure. Surgeons can easily observe the fundus in almost the whole area and evaluate the retinal pathologies through the panoramic view even in eyes with small pupils, corneal opacity, or eyes implanted ...

View-Angle of Spatial Data Mining
2006In order to discover the knowledge with various granularities from amounts of spatial data, a view-angle of spatial data mining is proposed. First, the view-angle of spatial data mining is defined. In its context, the essentials of spatial data mining are further developed. And the view-angle based algorithms are also presented. Second, the view-angles
