摘要： Provided is an apparatus and method for generating an image for character region extraction. Upon input of an original image, a candidate character image is generated from the original image and a plurality of binarization maps for similar colors are generated from the generated candidate character image. A binarization map including a background region is selected from among the plurality of generated binarization maps, and the background region of the selected binarization map is expanded. The expanded background region is inverted to generate an image including a character region, thereby generating an image for accurately extracting the character region without missing a boundary portion of a character.

摘要： A method is provided for automatically adjusting a size of characters using a camera. The method includes receiving an image with characters; adjusting a focus of the image with characters and detecting a region and a size of characters in the image; determining whether the size of the characters in the image falls within a preset range; recognizing the characters in the image and displaying the recognition results, if the size of characters falls within the preset range; and automatically adjusting a zoom ratio of the image and recognizing the characters in the resized image, if the size of the characters does not fall within the preset range.

摘要： Disclosed is a method and an apparatus for recognizing a character and efficiently removing a misrecognized character. The method includes detecting character regions including at least one character in an input image, converting the input image into a binary image, discriminating the characters from a non-character, re-classifying the character region including a number of characters equal to or less than a threshold into a non-character region, and outputting only the characters present in the character region.
