The paper presents a case of an aneurysm of the vein of Galen (VGA) in an infant, successfully treated by total open surgical excision (after previous ineffective embolisation). Current strategies of management of these rare yet potentially disastrous lesions are discussed and pertinent literature is reviewed.

A newly developed high-performance multiimager VGA camera array is described. Designed for synchronization, bandwidth, and economy within a videoconferencing application, and demonstrated initially through novel video mosaicking, the system shows promise for accelerating the new field of multi-viewpoint imaging. We describe the camera system’s design, control, performance characteristics, use i...

This article describes an FPGA-based implementation of the Harris-Affine feature detector introduced by Mikolajczyk and Schmid [1, 2]. The system is implemented on the Transmogrifier-4, a prototyping platform that includes four Altera Stratix S80 FPGAs and NTSC/VGA video interfaces. The system achieves a speed of 90–9000 times the speed of an equivalent software implementation, allowing it to p...

We present a novel multi-view dataset for evaluating modelfree action recognition systems. Superior to existing datasets, it covers 56 distinct action classes. Each of them was performed ten times by remotely controlled Sony ERS-7 AIBO robot dogs observed by six distributed and synchronized cameras at 17 fps and VGA resolution. In total, our dataset contains 576 sequences. Baseline results show...

Camera phone sales are expected to surge. Gartner, an IT research and advisory firm, predicts that sales will nearly double this year, from 80 million in 2003 to 150 million in 2004. The Zelos Group of Oyster Bay, N.Y., predicts that one-third of cell phone users will have camera phones in 2008. Most users will have phone cameras with VGA resolution clarity or less, according to Zelos Group. Bu...

A new OTA-based logarithmic-control variable gain current amplifier (LCCA) is presented. It consists of two Operational Transconductance Amplifier (OTA) and two PMOS transistors biased in weak inversion region. The circuit operates from 0.6V DC power supply and consumes 0.6 μW. The linear-dB controllable output range is 43 dB with maximum error less than 0.5dB. The functionality of the proposed...

A simple video game 'snake' is introduced in this report. The project was based on the embedded system design which required both hardware and software implementation. Digilent Nexys2 development board and Xilinx EDK platform were employed in this project. The project was divided into two parts: the hardware was designed by Yuan Mengze, which contained a VGA controller and a PS2 keyboard contro...
