14. The system of claim 13 , wherein the text-detection module comprises: a gray-level conversion module, the gray-level conversion module converting the image to a gray-level version of the image to form a gray-level image; a filtering and thresholding module, the filtering and thresholding module filtering and thresholding the gray-level image to emphasize bar-like and line-like regions which potentially correspond to the text, to form a first image; a line-removal module, the line-removal module removing long straight lines and rectangles from the first image to form a second image; a character-finding module, the character-finding module identifying potential text regions in the second image based on predefined character constraints to form a third image; a word-finding module, the word-finding module removing potential text regions from the third image which are not consistent with words to create a fourth image; and an output text-image-creation module, the output text-image-creation module creating the output image and the at least one gray-level image chip from the fourth image.
