A Method of Repairing Figure Strokes Based On End-point Direction

To deal with the feature extraction difficulty caused by figure stroke break or stroke fusion in image recognition, a method based on coupling end-point direction is put forward to repair the broken stroke. The following steps of image pretreatment, end-point extraction, distinguishing coupling end-point and repairing figure are illustrated taking the number plate image recognition as an application. And the results of simulation experiments are given, before-repaired and after-repaired figures are compared.
