Vehicle number plate detection in outdoor images

Robustness and efficiency are paramount for number plate detection and recognition systems to ensure their practicality for current day applications. This paper presents algorithms that determine the location of a number plate within still images, with the focus on robustness and efficiency. The number plate locating algorithms exploit the number plate’s signature in order to determine its bounding region. Complex images that contain a significant amount of irrelevant background data were used ensuring the robustness of algorithms developed. Efficiency was gained by removing irrelevant information prior to searching for the number plate signature through the use of pre-processing steps.
