摘要

运用随机分形特征描述了车牌字符的形态、复杂程度和不规则性特征

结合小波变换

使得车牌字符的分形特征描述更加丰富

同时避免了分形维数计算阈值选择带来的问题.模拟结果表明分形和小波结合使用的方法为车牌字符识别提供了新途径

但计算量较大.

Abstract

This paper uses random fractal character to describe the shape of vehicle license character

its complexity and characteristics.At the same time

it solves the problem that was caused by the chosen threshold when calculating the fractal dimension.Simulation results show that the method joining the fractal to wavelet is a new feasible approach to recognize vehicle license characters.But it should be mentioned that the calculation is mass.
