摘要

随着现代社会的发展,信息的形式和数量正在迅猛增长。其中很大一部分是图像,图像可以把事物生动地呈现在我们面前,让我们更直观地接受信息。同时,计算机已经作为一种人们普遍使用的工具为人们的生产生活服务。从图像中提取文字属于信息智能化处理的前沿课题,是当前人工智能与模式识别领域中的研究热点。由于文字具有高级语义特征,对图片内容的理解、索引、检索具有重要作用,因此,研究图片文字提取具有重要的实际意义。又由于静态图像文字提取是动态图像文字提取的基础,故着重介绍了静态图像文字提取技术。

Abstract

With the development of society,the form and quantity of imformation are increasing quickly.A large part of them are images,which can make things vividly presented in front of us,let us more intuitive to accept information.At the same time, the computer has been as a widely used tool for people's production and living services.Extracting text from image belongs to the frontier of intelligent information processing, and it is the current hot research topic in the field of artificial intelligence and pattern recognition.As the text with high-level semantic feature and plays an important role on understanding,indexing and retrieval image content.Therefore,the study on extracting texts from images have important actual meanings. And because extracting texts from still images is the basis for extracting texts from dynamic images, the article emphatically introduces the technology of extracting texts from still images.
