Among a number of studies which have investigated various speech enhancement and processing schemes for in-vehicle speech systems, the delay-and-sum beamforming (DASB) and adaptive beamforming are two typical methods that both have their advantages and disadvantages. In this paper, we propose a novel combined fixed/adaptive beamforming solution (CFA-BF) based on previous work for speech enhance...

utomatic Number plate recognition is a real time embedded system which identifies the characters directly from the image of the vehicle Number plate. Due to rapid development of technology and increasing use of vehicles, Number plate recognition has become necessary and it is playing an important role in variety of applications related to automated transport system such as road traffic monitori...

This work proposes a method for the detection and identification of parked vehicles stationed. This technique composed many algorithms for the detection, localization, segmentation, extraction and recognition of number plates in images. It is acts of a technology of image processing used to identify the vehicles by their number plates. Knowing that we work on images whose level of gray is sampl...

In this article, we consider abstract linear conservative systems and their time-discrete counterparts. Our main result is a representation formula expressing solutions of the continuous model through the solution of the corresponding time-discrete one. As an application, we show how observability properties for the time continuous model yield uniform (with respect to the time-step) observabili...

Automatic number plate recognition is the task of extracting vehicle registration plates and labeling it for its underlying identity number. It uses optical character recognition on images to read symbols present on the number plates. Generally, numberplate recognition system includes plate localization, segmentation, character extraction and labeling. This research paper describes machine lear...

The paper outlines the development and design of a speech driven control for a personal in-car navigation system which runs on a standard Pocket PC. The modified system enables speech driven menu navigation, speech shortcut commands and interactive dialogues. The speech recognition method is presented, sources of inaccurate recognition are identified, and solutions are presented. Speech recogni...

In a former work, we built a VLP (Vehicle License Plates) reader using computer vision. To test other methods, we decided to implement a whole new system from scratch. In this communication, we summarize the methods that we have tested and the results we have obtained. Plate location is based on mathematical morphology and character recognition is implemented using Hausdorff distance. Results a...

In recent years, many researches on Intelligent Transportation Systems (ITS) have been reported. Automatic License Plate Recognition (ALPR) is one form of ITS technology that not only recognizes and counts vehicles, but distinguishes each as unique by recognizing and recording the license plate’s characters. This paper discusses the main techniques of ALPR. Several open problems are proposed at...
