360 x 360 Mosaics

Current mosaicing methods use narrow field of view cameras to acquire image data. This poses problems when computing a complete spherical mosaic. First, a large number of images are needed to capture a sphere. Second, errors in mosaicing make it difficult to complete the spherical mosaic without seams. Third, with a hand-held camera it is hard for the user to ensure complete coverage of the sph...

We are studying the geometry of a 360 x 360 mosaic image formation. A 360 x 360 mosaic camera model and a calibration procedure are proposed. It is shown that only one point correspondence is needed in order to acquire epipolarily rectified images. The 360 x 360 mosaic camera model is therefore determined by only one intrinsic parameter. It is shown that the relation between coordinates estimat...

The paper describes the history of viscous-inviscid interaction methods, and tries to put them in a modern domain-decomposition context. This history started in 1904, when Ludwig Prandtl presented thèboundary layer' at the Third International Mathematical Congress in Heidelberg. From that moment on, the ow eld around a body was divided in two parts: a thin shear layer where viscosity plays a ro...

Cataract surgery is the most common elective operation performed worldwide (1, 2). The development of new technologies and new surgical techniques and materials lead to less invasive and day care procedures. This in turn encouraged an evolution on the ophthalmic anesthetic strategies, rendering general anesthesia largely unnecessary, so that local techniques have become preferred for cataract s...
