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

نویسندگان

چکیده مقاله:

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 morphological approaches and improved them by using adaptive techniques to achieve more compatibility with practical applications. We examined the developed system on several car plate image databases with different conditions like different camera distance, and different car views. The average achieved rate of success was 89.95% for car plate location recognition, which is around 6.0% higher than previous related report of morphological methods. We further implemented the system on an FPGA platform.

License Plate Recognition System

This paper presents a novel method of identifying and recognizing license plates, required by an automatic vehicle identification system. The main challenge was the isolation of the car’s license plate, from the digital image acquired by the video system, under different illumination conditions and various angles. Thus, we have established the required preprocessing operations leading to succes...

Real Time Localization, Tracking and Recognition of Vehicle License Plate

Real time license plate localization, tracking and recognition are reasonably tackled problems with many successful solutions. Though most of these solutions are plausibly fast and efficient, however, almost all of the existing real time systems either deal with only a single problem at a time; detection, tracking, recognition or they are not efficient enough to work well for low quality survei...
