Natural scenes contain a large quantity of image information

but also plenty of text information. These text characters could offer important semantic information. Automatic detection and recognition of text in natural scene images is an important research topic in pattern recognition and image processing. In this paper

we propose an effective method to extract text from scene images. The main idea is as follows:First

an edge detection method is used for coarsely locating the text areas

then we apply a gray based detection scheme to the located areas in order to confirm the found characters. Finally

the noise regions are removed through filtering all the detected regions

and the target text regions are obtained. Experimental results show that our scheme is robust on finding text in natural scene images with respect to different font sizes

styles

colors and orientations.In this way

the text information can be located and extracted accurately.
