光电混合内积型关联识别系统

提出把图象信息提取与光学内积关联技术结合起来识别图象的方法,并按照此原理,设计与组建了一个光电混合图象信息提取与关联识别系统。用0～9十个印刷体阿拉伯数字和八种中外飞机作为试验目标在系统上进行了识别实验。结果表明,印刷体数字和八种飞机的(可允许左右15°转动)识别率达100%,手写体数字的识别率也能达到70%左右。

AN OPTICAL HYBRID INNER-PRODUCT CORRELATOR FOR PATTERN RECOGNITION

A method o f combination of the nnage information extractlng and optical inner-product correlating techniques for pattern re cognition is presented in this paper, Accordingto this principle, an optical hybrid system consisting of an image ioformation e xtractor andan optical correlator was designed and set up in laboraton, Taking ten Aralyic numberalsfrom 0 t0 9 and eight varkius airplanes as the test targrts, their recognition were experimented. The experimental results show that, for printing Arabic numberals and the eightairplanes(they peimit to ro tate an angle of 15?)the recognized ratio reaches 100% and forhand-writing Arabic numberals about 70% of their recognition may be rcached.
