基于Fisher算法在手写识别系统中的应用

摘要

In order to achieve the intelligent recognition of mobile equipment input requirements, this paper designed a kind of single chip microcomputer intelligent handwritten recognition system. Based on the analysis of the Fisher linear differential algorithm, the carrier, with the single chip processor as the hardware realization of Fisher linear identification algorithm in the application of handwriting recognition. The hardware part mainly use STM32F407 MCU as the core, the programming to realize the Fisher linear differential algorithm, in the process of the experiment many times with different character recognition. Experiments show that the system has simple operation and high recognition rate and recognition speed, has practical use value, meet the design requirements.%为了实现智能移动设备输入识别的需求，文中设计了一种单片机实现智能手写识别系统。在分析Fisher线性鉴别算法的基础上，以单片机为硬件载体，实现Fisher线性鉴别算法在手写识别中的应用。该系统的硬件部分主要使用STM32F407单片机为核心，编程实现Fisher线性鉴别算法，实验过程中对不同字符进行多次识别。实验表明该系统具有操作简单、识别率高、识别速度快等优点，具有实际使用价值，达到设计要求。
