Character Recognition And MCU Display

Character recognition is one of the popular application researches in the world. Thisarticle through to preprocess the image, image segmentation, programming, proposes acomprehensive method of character recognition, and using single-chip system to build adrive circuit and display circuit, mainly to complete the following three parts.Extracting a feature identification. To determine the threshold selection based ongray-scale image histogram split images into a single character, to locate the characterimage segmentation, and take full advantage of the characteristics of the image of alicense, using a standard template Statistics Act, reached a high recognition rate.The features of numbers will be extracted using software like Matlab and programmedfor the single-chip system. The extracted binary matrixes will be transformed intohexadecimal codes, which can be identified and displayed on the single-chip system.The whole system is composed of a single-chip clocking circuit, a driver circuit and adisplay circuit. The clocking circuit provides a stable functioning environment while thedriver circuit defines the dimensions of the lattice through PO and P3ports to make thedisplay accurate.
