The walk-through FogScreen has become very popular and famous during recent years. It is an immaterial projection screen that consists of air and a little humidity, and enables high-quality projected images in thin air, as well as many new applications. In this paper we describe a new extension, the interactive FogScreen, which turns it into a computer touch screen.

Temporal intensity flicker is a common artifact in old film sequences. Removing disturbing temporal fluctuations in image intensities is desirable because it increases both the subjective quality and, where image sequences are stored in a compressed format, the coding efficiency. We describe a robust technique that corrects intensity flicker automatically by equalizing local frame means and var...

Chronic aspirin ingestion in childhood is not uncommon, often goes undetected, and may cause serious anaemia from occult blood loss. Five cases are described.

Abstract In this article, a new method for processing trajectory parameter tests of flying targets with the geometric center screen as response time detector is proposed. The superiority over conventional uniform thickness treatment shown through error and data analysis yaw angle, pitch speed. relative distance between test track real shows accuracy method. obvious statistical rules can be foun...

This document is a summary of the goals, current status and future schedule of the multi-year collaborative proposal [1] to the CfAO “Development, implementation and validation of PSF reconstruction techniques.” The project started in November 2007 at the W. M. Keck Observatory (WMKO) under the direction of D. Le Mignant (PI), with postdoctoral researcher R. Flicker employed for the principal a...
