Abstract
A method for extracting text from images whereby the intensity of each color plane of the image is identified, the color plane with the highest intensity is converted into a black and white image, and character recognition is performed on the black and white image to determine the text of the image. The method can be used for textual word searches for Graphics Image Format (GIF) images as well as Joint Photographic Experts Group (JPEG) images, thereby providing the capability to perform text searches for images found on web pages of the World Wide Web.
