介绍图像中字符区域检测算法的研究：图像中的文字信息在一定程度上反映了图像主要内容，因此对于图像中的文字进行检测是非常有意义的。本文采用了基于字符的纹理特征的方法，在D C T 域中对字符进行检测，从而将图像中的字符区域检测出来，最后用matlab进行了验证，实验表明该方法能够取得较好结果。-Introduction character image region detection algorithm research: images of a text message to some extent, reflect the main content of the image, so the text in the image test is very meaningful. In this paper, a character-based method of texture features, in the DCT domain detection of the characters, so characters in the image region detected, and finally use matlab to verify the experiment shows that the method can achieve better results.
