An augmented method for finding character lines in a gray scene image is proposed. In the proposed approach, we use several heuristics of both characters (such as size, symmetry of pixels and bimodality of intensity histogram) and character lines (such as proximity of characters and alignment of arrangement) to discriminate characters from other objects in a scene image. Experimental results indicated that the method performed well for signboards imaged from a relatively wide range of viewing directions.
