Abstract:

This paper does the“and” operation for the pre-designed template standard of license plate character and the character to be recognized.It puts forward two discriminant functions,calculates the minimum of standard deviation of the template,the character to be recognized and the matching result,calculates the maximum sum of the matrix elements of the matching result,and makes an analysis of their results.Then it uses them together.The results show that it has better result than the previous method in recognition of some characters.
