基于并行模糊神经网络的车牌识别研究

车辆牌照的自动识别是目标自动识别的一种重要形式,针对车牌识别的后期技术,即牌照识别技术做了研究并提出了一种新的车牌识别方法,该网络由BP神经网络识别模块和模糊控制器构成,为了便于硬件实现,各模块相互独立,最后利用PVM网络在虚拟并行平台上实现了该识别网络,实验结果表明,和标准BP网络相比,该算法具有更加良好的性能,满足实时识别车牌的要求。

Parallel Implementation of Global Illumination Using PVM

In this paper an attempt of employing network resources to solve a complex and time-consuming problem is presented. The global illumination problem is selected as the study objective. An improved density estimation algorithm is first developed, in which the more inherent concurrency is explored. Then its parallel implementation by using a PVM mechanism and the running performance analysis are provided. The analysis results show the expected speed-up obtained and demonstrate that the PVM has good application prospects for parallel computation in a distributed network.

复杂环境中的车牌字母和数字识别研究

当前车牌识别的研究大都是针对正常环境进行的,对于复杂环境下的车牌难以达到识别要求。本文提出一种用BP神经网络构造并行神经网络的车牌字母和数字识别方法,利用PVM网络在虚拟并行平台上实现了并行神经网络,最后对复杂现场环境下获取的车牌进行了实验。实验结果证明,该算法具有良好的性能,能在28ms内实时准确的识别车牌字母和数字。
