This paper describes the Real-Time Vision System (RVS-2) which shows quite high performance for low-level image processing while it is implemented in compact size. The RVS-2 consists of a IMAP board, a video board and a host workstation and the IMAP board consists of eight highly integrated IMAP LSIs and a dedicated control LSI(RVSC). The IMAP chip integrates 2Mbytes image memory and 64 process...

Hyperspectral imaging is a powerful remote sensing technology, but its use in space limited by the large volume of data it produces, which leads to downlink bottleneck. Therefore, most payloads date have been oriented towards demonstrating scientific usefulness hyperspectral sporadically over diverse areas rather than detailed monitoring spatio-spectral dynamics. The key overcoming bandwidth li...

Mitsubishi Electric Neuro4 is a high performance parallel processing engine for neural network, image processing and signal processing applications. The Neuro4 chip employs a distributed memory SIMD architecture with twelve 24-bit floating-point processing units (PUs), a nonlinear function unit (NFU), and a control unit (CU). A Neuro4 board consists of four Neuro4 chips. In this paper, we prese...

In this study, Field-Programmable Gate Arrays (FPGAs) are investigated as a practical solution to the challenge of designing an optimal platform for implementing algorithms in a wireless sensing unit for structural health monitoring. Inherent advantages, such as tremendous processing power, coupled with reconfigurable and flexible architecture render FPGAs a prime candidate for the processing c...

We present a quad-rotor micro aerial vehicle (MAV) that is capable to fly and navigate autonomously in an unknown environment. The only sensory input used by the MAV are the imagery from two cameras in a stereo configuration, and data from an inertial measurement unit. We apply a fast sparse stereo matching algorithm in combination with a visual odometry method based on PTAM to estimate the cur...

* This work was supported by the U.S. DOE Contract No. DE-AC05-84-ER40150 Abstract A Dual Digital Signal Processing VME Board was developed for the Continuous Electron Beam Accelerator Facility (CEBAF) Beam Current Monitor (BCM) system at Jefferson Lab. It is a versatile general-purpose digital signal processing board using an open architecture, which allows for adaptation to various applicatio...

This application note shows how to achieve low-cost, efficient serial configuration for Spartan FPGA designs. The approach recommended here takes advantage of unused resources in a design, thereby reducing the cost, part count, memory size, and board space associated with the serial configuration circuitry. As a result, neither processor nor PROM needs to be fully dedicated to performing Sparta...

People are motivated according to their needs. These needs vary according to the time and based on various situations. Identifying and assessing human needs are the first and vital step in determining the amount of its impact on work and activity. According to these facts, the aim of this research is to identify the needs of the Iranian seafarers on board merchant ships. It also tries to spec...
