Machine vision and automated processing systems are under development at Virginia Tech University with support and cooperation from the USDA Forest Service. Our goals are to help U.S. hardwood producers automate, reduce costs, increase product volume and value recovery, and market higher value, more accurately graded and described products. Any vision system is composed of two bread tasks: imag...

A board is described that contains the ANN A neural-network chip, and a DSP32C digital signal processor. The ANNA (Analog Neural Network Arithmetic unit) chip performs mixed analog/digital processing. The combination of ANNA with the DSP allows high-speed, end-to-end execution of numerous signal-processing applications, including the preprocessing, the neural-net calculations, and the postproce...

On-board data systems and data handling electronics are in constant evolution, due to the obsolescence of components and indeed to the need of increasing their performances. They follow ground technology trends, often at a slower pace, such as the ones allowing easier and faster integration by reusing building blocks. This is well reflected by on-board platform and payload computers that become...

Nova Sensors produces miniature electronics for a variety of real-time digital video camera systems, including foveal sensors based on Nova’s Variable Acuity Superpixel Imager (VASITM) technology. An advanced imageprocessing package has been designed at Nova Sensors to re-configure the FPGA-based co-processor board for numerous applications including motion detection, optical, background veloci...

The exact reconstruction and restoration of perceived image and its properties such as shape, illumination are the severe problem in an image processing field. This problem can be successfully overcome through efficient computer vision algorithm. This paper presents an attempt to implement image processing algorithm on embedded hardware provided by low cost processor from Texas Instruments (TI)...

Previous studies have found that block play, board games, and puzzles result in better spatial ability. This study focused on examining the differential impact of structured block play and board games on spatial processing. Two groups of 8-year-old children were studied. One group participated in a five session block play training paradigm and the second group had a similar training protocol bu...

This paper describes how the correct endian mode of the TMS320C6713 DSK board can be identified. It also explains how the TMS320C6713 DSK board can be used in the little endian and in the big endian modes for assembly language programming in particular and for signal processing in general. Similarly, it discusses how crucially important it is for a user of the TMS320C6713 DSK board to identify ...

Abstract Objectives The main objective was to gain more knowledge on exposure bioaerosols in the processing area board fishing trawlers. Methods Exposure sampling carried out during work shifts when fish five deep-sea trawlers (trawlers 1–5). samples were collected from 64 fishermen breathing zone and stationary stations (1–5). Trawlers 2, 3, 4 old ships, not originally built for of catch. 1 5 ...

Synthetic aperture radar is a microwave technique to extracting image information of the target. Electromagnetic waves that are reflected from target acquired by aircraft or satellite receivers and sent ground station be processed applying computational demanding algorithms. Radar data streams an in order extract images since these processing algorithms computationally demanding. However, novel...
