Abstract
Characters are located in a character recognition system by providing images in response to scanning characters, and then smearing black pixels in an image in up and down and left and right directions for detecting corners which are used to produce candidate character frames. These candidate character frames are scored based on how well they correspond to character size and expected location to determine which character frames are to be submitted for character recognition.
