【摘要】 图形识别是模式识别的一个重要分支。通过对待识别图形提取7个不变矩,然后将其送入概率神经网络加以识别,以达到对图形进行分类的目的。试验结果表明,该方法不仅能对通常的图形进行分类,而且能对有缺损、畸变的图形进行分类。更多还原

【Abstract】 Recognition of graphic pattern is a branch of pattern recognition. In this paper, firstly, seven invariant moments of graphics as well as its features are obtained. Then, these features are sent to probabilistic neural network for recognition. Experiments show that this method not only can classify ordinary graphic patterns, but also can classify defective or lopsided graphic patterns.更多还原
