静态图像提取文字技术

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，总结了几种已提出的算法，并利用计算机语言学方法对提取出的文字进行后期处理，大大提高了文字提取的正确率。

The Technology of Extracting Texts from Still Images

Extracting the text from images belongs to the frontier topics on intelligent information processing,and it is the current research focus in 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 and summarized some kinds of proposed algorithms. The statistical methods based on computer linguistics used to post-processing the extracted text has greatly enhanced the correct rate of text extraction.
