Pattern recognition is very challenging multidisciplinary research area attracting researchers and practitioners. Gesture recognition is a specialized pattern recognition task with the goal of interpreting human gestures via mathematical models. One of the usages of gesture recognition is the sign language recognition which is the basic communication method(More)
License Plate Recognition (LPR) has a lot of applications in various fields. It is a mass surveillance method that uses an optical character recognition method to read vehicle registration plates. LPR system is mainly used in parking lots, tolling booths and nowadays in the signal system in order to identify the vehicle that crosses the line before the(More)
Till now many optimization algorithms are available for solving complex problems. The algorithm that has created an impact is the numerical function optimization. Some of the existing optimization algorithms are classified into evolutionary computing and metaheuristic methods. A comprehensive survey on numerical function optimization is presented below with(More)
License Plate Recognition (LPR) is a well known image processing technology. LPR system consists of four steps: capture the image from digital camera, pre-processing, character segmentation and character recognition. License plates are available in various styles and colors in various countries. Every country has their own license plate format. So each(More)
Improving visual clarity of an image is conveniently achieved by various contrast enhancement techniques. Histogram equalization results in excess contrast enhancement. When fuzzy concepts are used for color image enhancement it creates visual artifacts. But contrast enhancement using ACO (Ant Colony Optimization) technique avoids excess contrast(More)
— Document digitization and Document Analysis and Recognition (DAR) are techniques that are used for handling document images. Several techniques were implemented to perform document digitization. Article reconstruction is one of the main applications of document digitization. The four major steps of article reconstruction are grouping the article bodies,(More)
