摘要提出一种用共线点列标定摄像机镜头畸变参数的方法，先根据交叉比不变性确定畸变中心，再利用直线的中心投影仍为直线这一性质确定畸变系数。 - In this paper , we extract the llf ( local line fitting ) , cpt ( central project transform ) and chain code features of characters , and then combine them with the statistical and structural information of characters for character recognition
本文在手写体字符特征提取方法研究中，通过对手写体字符的研究，提取了字符的llf 、中心投影、链码等特征，并将这些特征与传统的字符统计特征和结构特征相结合应用于手写体字符识别系统。 - In view of the feature of neural network and its advantages in pattern recognition , we have a great deal work in off - line handwritten character recognition based on neural network . we present two recognition methods based on neural network . one of which is the hybrid neural network recognition system , a multi - level neural network classifier constructed by using the multi neural networks integration technology
由于神经网络的特点及其在手写体字符识别领域体现出的潜力，本文对基于神经网络的手写体字符识别技术进行了大量的研究工作，提出了两种新颖的基于神经网络的手写体字符识别模型，其中，基于混合神经网络的手写体字符识别模型利用了在抗干扰和描述字符拓扑结构方面具有互补性的中心投影特征和llf特征，使用多神经网络集成技术构建了多级的神经网络分类器。
