The invention relates to fast processing techniques designed for enhancing the pictorial contents of digital holograms, without the need to reconstruct the original 3D scene. The hologram is back-projected to a hypothetical 2D image known as virtual diffraction plane (VDP). The VDP is then processed.....

This invention relates in general to real-time voice and video communication over the Internet, and in particular, to systems for managing the voice and video streams when conversational speech patterns are considered. A SAVV client and corresponding SAVV algorithms are proposed. The SAVV client can.....

A novel technology for the measurement and surface reconstruction of a 3D image of an object is developed. The method proposed comprises the projection of a pattern onto the surface to be imaged, the examination of distortion incurred on the pattern by the surface, and the conversion of distortion b.....

Conventional digital holography involves a high amount of computation to generate an object scene, imposing a significant bottleneck to practical applications. The invention presents techniques for efficiently generating full parallel 3D holographic images of a 3D real or synthetic object scene. The.....

An economical and versatile approach is developed to construct photonic structures using well-established solution-based deposition and post-deposition modification techniques. Without sophisticated and expensive vacuum equipment or control systems, such an approach can achieve elaborate periodic mi.....
