متن کاملText Extraction from Gray Scale Document Images Using Edge Information
In this paper we present a well designed method that makes use of edge information to extract textual blocks from gray scale document images. It aims at detecting textual regions on heavy noise infected newspaper images and separate them from graphical regions. The algorithm traces the feature points in different entities and then groups those edge points of textual regions. From using the tech...

Images and videos on webs and in databases are increasing. It is a pressing task to develop effective methods to manage and retrieve these multimedia resources by their content. Text, which carries high-level semantic information, is a kind of important object that is useful for this task.When a machine generated text is printed against clean backgrounds, it can be converted to a computer reada...
متن کاملText Extraction from Images
Automatic image annotation, structuring of images, content-based information indexing and retrieval are based on the textual data present in those images. Text extraction from images is an extremely difficult and challenging job due to the variations in the text such as text scripts, style, font, size, color, alignment and orientation; and due to extrinsic factors such as low image contrast (te...
