一种模拟人眼—脑系统的条形码图像处理与分析技术

A TECHNIQUE OF BAR CODE IMAGE PROCESSING AND ANALYSING SIMULATES EYE-BRAIN SYSTEM

As density of bar code is increasing constantly, reading and processing of bar code, especially 2-D bar code, are faced with more and more serious difficulty in CCD camera system of high resolving power, memory volume of computer image, and speed of image processing. In this paper bar code images are processed and analysed with simulated human eye-brain system from bionics, and bar code images are described with area element as visual symbols. The structure of syntactical image will discribed with area element as visual symbols. The structure of syntactical image compresses volume of computer image memory effectively. And structural or syntactical image analysis becomes very simple and fast. The relative area value is used in decode processing directly. This article also analyses to describe the required accuracy of symbol formation is analysed.
