The features of Mathematical Morphology are quick and brief function and so on.The paper uses Mathematical Morphology for the vehicle license recognition.After the pretreatment and threshold values segmentation,the erosion operation of Morphology is to edge detection and recognition of the vehicle license.The way is going to detect only pixel of edge breadth of the object,so it is high position precision.Finally,the matlab 7.0 is used to simulate the images.A lot of experiments show that,the algorithm is of...
