【摘要】 对基于人工神经网络的文字识别(OCR)进行了深入的研究,给出了用于车辆牌照识别特征的提取方法,构建了一个三层BP网络用于识别。实验结果表明,该方法简单,识别率高,对噪声不敏感,可推广到多种OCR识别中。更多还原

【Abstract】 OCR based on neural network is further studied in this paper. Method used for recognizing the license plate is give and a three-layer BP network is constructed. Experiments have shown that this method is simple,insensitive to noise and has a high recognition rate. This method can be applied to many OCR recognitions.更多还原
