| 摘 要： | 建立了基于联合变换的兴电混合处理系统，对文字进行了相关识别；提出一种便于实际使用的评判相关识别度的参量指数，采用两种对联合变换功率谱进行非线性滤波处理的方法．系统运行结果表明，这两种方法都有效地提高了文字的相关识别度． |
| 关 键 词： | 联合变换 光电混合处理 相关识别度 功率谱 非线性滤波 |

| Abstract: | An optical electronic hybrid system on joint transform has been set up for automatic identification of Chinese characters. A criterion is defined which can be easily used in correlation reeognition and two nonlinear processing methods for improving correlation effects are proposed. |
| Keywords: | joint transform optical electronic hybrid processing correlation identification level power spectrum nonliinear filtering |
