一、引言在很多领域内都出现图样识别问题,例如:医学(血球分类、癌细胞分类等等);通讯(自动语言识别及字码—数码识别);气象(天气图识别);刑事科学(指纹识别)以及军事科学(摄影图片分析、雷达与声纳目标信号的自动识别,其他等等)。尽管上述问题以及许多其他问题在近年来受到极大的注意,然而进展仍很缓慢。获得充分成功足以在实际环境中被采用的系统为数甚少。而在这种系统中其设计主要是靠设计者的经验和直观。某些情况下是由于图样本身具有明显差别使问题变得很简单才获得成功的。通
I. INTRODUCTION Pattern recognition problems occur in many fields, such as: medicine (blood cell classification, cancer cell classification, etc.); communication (automatic speech recognition and word code - digital recognition); weather (weather map recognition); criminal science Fingerprinting) and military science (photographic image analysis, automatic recognition of radar and sonar target signals, others, etc.). Despite these and many other issues, which have received tremendous attention in recent years, progress is still slow. There are very few systems that have been sufficiently successful to be adopted in the real world. In this system, its design is mainly based on the designer’s experience and intuitive. In some cases, success is due to the obvious differences in the patterns themselves that make the problem easy. through
