Disc Defect Handling in Optical Disc Drives

This report is on the handling of disc defects in optical disc drives. The goal of the research is to investigate how the influence of disc defects can be characterized and utilized on the servo level, in order to achieve playability improvement. After a general introduction on optical disc drives, three aspects of the problem are treated in detail. From extensive measurements and theirasubsequ...

3D Surface Reconstruction of Optical Disc

This article deals with retinal surface reconstruction obtained with the fundus camera. Two stereo images (photographs) are used to estimate the disparity, which is connected to the depth in the scene. New gradient-based method is used to perform the first estimate of disparity, followed by several postprocessing steps to eliminate errors.

Computer Animation via Optical Video Disc

This paper explores the notion of marrying two technologies: raster-scan computer animation and optical video discs. Animated sequences, generated at non real-time rates, then transfered to video disc, can be recalled under user control at real-time rates. Highly detailed animation may be combined with other media in interactive systems. Such systems inherently offer a greater degree of flexibl...

Optical disc storage: another can of worms?

The University Grants Committee and the Computer Board have funded 139 projects in Bntish Umversities as part of their Computers in Teaching Initiative. Two projects have been accepted m archaeology, a joint Southampton/York project on simulating an excavation and an mvestigation at Leicester into the use of interactive videodiscs for teaching archaeology to undergraduates. This paper introduce...
