This document describes a FPGA implementation of an optical flow correlation based detection method which is very fast (with low accuracy) and allows near real time applications (6 frames/second) on standard computing hardware. It manages the motion estimation problem with a speed restriction, obtained from an image down sample process, that yields image(More)
A FPGA based hardware implementation of the Santos-Victor optical flow algorithm, useful in robot guidance applications, is described in this paper. The system used to do this task contains an ALTERA FPGA (20K100), an interface with a digital camera, three VRAM memories to contain the data input and some output memories (a VRAM and a EDO) to contain the(More)
This article approaches a detailed analysis of hybrid vehicles and their components by using a mathematical model programmed in Matlab Simulink. This model has been developed to enable students to adopt a global approach, tackling aspects of different subjects of Mechanical Engineering studies. The program is also used to supplement practical laboratory(More)
This paper describes an electronic system designed for real-time vision applications. The system will allow the development of low-complexity tasks, such as obstacle detection, at very high frequencies. This makes it useful for robotic applications and control systems in real time (up to 25 images per second). Its design has taken into account low-cost and(More)
Depending on their frequency, radio waves can be absorbed by water and biological tissues (Bottomley & Andrew, 1978). They can also be shielded by metals due to the eddy currents. These effects constitute a huge problem for the implementation of radio frequency identification (RFID) systems in real environments. RFID systems can be classified into three(More)
