APPARATUS AND METHOD FOR EXTRACTING CHARACTER OF IMAGE

摘要

Provided is an apparatus and method for extracting character(s) from an image. The apparatus includes a mask detector detecting a height of a mask indicating a character(s) region from spatial information of the image created when detecting a caption region comprising the character(s) region and a background region from the image and a character(s) extractor extracting character(s) from the character(s) region corresponding to the height of the mask. The spatial information includes an edge gradient of the image. Therefore, the apparatus extracts important information from an image and can recognize small character(s) that is not recognizable using conventional methods. In addition, an image can be more accurately identified, summarized, searched, and indexed according to contents by recognizing extracted character(s). Further, the apparatus enables faster character(s) extraction.
