文本是计算机视觉的许多应用中的一项重要特征。大量复杂图像文本的应用， 使图像文本分析技术成为研究的新方向。

图像文本分析技术和通常的文档图像分析技术之间有着紧密的联系； 但是图像文本其自身所具有的特性， 又使得图像文本分析技术

具有不同于一般的文档图像分析的更加丰富的内容。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。最后， 本文也对图像文本分析技术的应用进行了讨论。-The text is in many applications of computer vision is an important feature. Application of a large number of complex images of text, image text analysis technology to become the new direction. Image text analysis technology and document image analysis usually has a close connection　but the image text possess its own characteristics, but also makes the image text analysis technology is different from the general document image analysis, richer content. We will image text analysis is divided into three components: the image text position, text, image preprocessing and image text recognition for discussion. Finally, the paper version of the image analysis technology were discussed.
