Automatic license plate recognition (LPR) plays an important role in numerous applications and a number of techniques have been proposed regarding the same. LPR is the extraction of vehicle license plate information from a captured image.[1] The extracted information can be used with or without databases in many applications such as electronic payment systems (parking fee payment) and monitoring system for traffic surveillance. LPR uses the camera from a smartphone to capture the image. The quality of the acquired images is a major factor in the success of the LPR. LPR as a real life application has to quickly and successfully process license plates under different environmental conditions such as day, night, and outdoors.[2] Image processing techniques that will be used are image detection, image binarization, character analysis, identification of plate edges, deskewing the image, character segmentation, optical character recognition, post processing for calculation of confidence.
