In this paper, techniques for image text analysis are divided into three main blocks: image text extraction, image text preprocessing and image text recognition.

我们将图像文本分析技术划分为三大组成部分：图像文本定位、图像文本的预处理和图像文本的识别进行讨论。

When its image-recognition software can't interpret a passage of aged or faded text, it further distorts the image and serves it up as a CAPTCHA. That means the project not only produces an enormous output of digitized records for preservation purposes--it also filters text to find far more difficult words for computers to recognize.
