Abstract: “Number plate recognition (NPR) is one of the most important applications of applying computer techniques towards intelligent transportation systems (ITS). In order to recognize a number plate efficiently, location and extraction of the number plate is the key step. Hence finding the position of a number plate in a vehicle image is considered to be the most crucial step of an NPR system, and this in turn greatly affects the recognition rate and overall speed of the whole system.”
