Real Time Implementation of a License Plate Location Recognition System Based on Adaptive Morphology

License plate recognition (LPR) by using morphology has the advantage of resistance to brightness changes; high speed processing, and low complexity. However these approaches are sensitive to the distance of the plate from the camera and imaging angle. Various assumptions reported in other works might be unrealistic and cause major problems in practical experiences. In this paper we considered ...

Real-Time Implementation of an Acoustic Echo Canceller on DSP

| Acoustic echo cancellation is an essential signal enhancement tool for teleconferencing applications such as hands-free telephony, tele-classing and video-conferencing. However, loudspeaker signals are picked up by a microphone and are fed back to the correspondent, resulting in an unde-sired echo. Nowadays, adaptive ltering techniques are typically employed to suppress this echo. In acoustic...

Real -Time Implementation of a Nearfield Broadband Acoustic Beamformer

The domain of array signal processing constitutes a field of study where many interesting and challenging projects can be undertaken. The work presented in this thesis is motivated by the implementation of a nearfield broadband beamformer using an array of acoustic sensors, which can be typically used for applications in speech acquisition. The objective of this work is to practically test this...

Animated Impostors for Real-Time Display of Numerous Virtual Humans

Rendering and animating in real-time a multitude of articulated characters presents a real challenge and few hardware systems are up to the task. Up to now little research has been conducted to tackle the issue of real-time rendering of numerous virtual humans. However, due to the growing interest in collaborative virtual environments the demand for numerous realistic avatars is becoming strong...
