Abstract

Video processing techniques in most of the current display systems are performed without considering the text information. The proposed algorithm aims to localize the text regions for video processing. To derive the robust text-like features, a statistical analysis is introduced. With the 2D structure analysis and multi-resolution refinement, most text regions are localized using the proposed text-like feature. 1

基于类文本特征统计分析的梯度视频文本定位算法
目前大多数显示系统的视频处理技术都没有考虑文本信息。该算法旨在对文本区域进行局部化处理。为了得到鲁棒的类文本特征,引入了统计分析。通过二维结构分析和多分辨率细化,利用所提出的类文本特征对大多数文本区域进行了定位。1
