Abstract
A method of locating a character set in a digital image comprises examining pixels of the digital image to detect pixels having specified color attributes. Regions of the detected pixels are identified and the identified regions are clustered according to color similarity. Each cluster is examined to detect the cluster meeting specified morphological constraints thereby to locate the character set. An apparatus for locating a character set in a digital image is also provided.
