Automatic license plate recognition (ALPR) is the extraction of vehicle license plate information from an image or a sequence of images. [...] Key Method We categorize different ALPR techniques according to the features they used for each stage, and compare them in terms of pros, cons, recognition accuracy, and processing speed. Future forecasts of ALPR are given at the end.Expand
