一种改进的数字图像定位识别方法研究
Research on an Improved Auto-locating and Recognition Method for Digital Images
摘要
Abstract
According to the requirement of the automatic recognition for digital video,an improved digits auto-locating and recognition method is presented. It adopts self-adaptive threshold for binarization of image and then an improved algorithm of Stroke Width Trans-form ( SWT) is designed to make a coarse locating of the digits' regions. After that,the precise positions of the digits are determined by filtering them with some useful features,such as its height-width-ratio,color and spatial arrangement,and the multi-level extension and merging is applied to eliminate the influence on shield and adhesion for the exact locating of digits region with perfection. At last,after extraction of the high discriminative features in digital regions,the digits can be accurately recognized and achieved by trained multi-clas-sified models,which can implement the automatic recognition of digits in videos. The experimental results show that the proposed method owns high accuracy and strong robustness,without impact on light,titlt and partial shield,and locate the correct digits regions for recogni-tion of digits. It is suitable for automatic inspection,remote meter reading and so on.关键词
