Analysis of Spatial domain and Frequency domain Techniques for Car plate detection
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 9
Abstract
In last couple of decades, the number of automobiles has increased drastically. With this increase, it is difficult to keep track of each automobile for purpose of law enforcement and traffic management. License Plate Recognition is used increasingly nowadays for automatic toll collection, maintaining traffic activities and law enforcement. Many techniques have been proposed for plate detection, each having its own advantages and disadvantages. The basic step in License Plate Detection is localization of number plate. The approaches mentioned in this work are a Spatial domain(Histogram Based Approach(HBA)) and transform domain(Steerable wavelet) for car license plate detection analysis is done for both approaches by performance measures like Peak signal to noise ratio(PSNR),Mean square error(MSE) and success ratio, consumption time. The transform domain technique using steerable wavelets seems to be promising for this application.
