摘要
介绍了图像文字识别中预处理技术的研究现状,依据预处理的实现过程,分析了降噪、数据校正、压缩技术的目的,并对降噪、数据校正、压缩技术的实现原理进行了深入讨论。
This paper presented that the current state of research about the preprocessing techniques in optical character recognition. According to the preprocessing process, the technologies of noise reduction, data normalization and compression are discussed separately. Further, the theory of noise reduction, data normalization and compression was analyzed deeply.
