ALPRS - A New Approach for License Plate Recognition Using the SIFT Algorithm

This paper presents a new approach for the automatic license plate recognition, which includes the SIFTalgorithm in step to locate the plate in the inputimage. In this new approach, besides the comparisonof thefeatures obtained with the SIFT algorithm, the correspondence between the spatial orientations and thepositioning associated with the keypoints is also observed. Afterwards, an algorithm is used for thecharacter recognition of the plates, very fast, which makes it possible its application in real time.Theresults obtained with the proposed approach presented very good success rates, so much for locating thecharacters in the input image, as for their recognition.
