<p>A hand-written character to be encoded is defined by digital data, typically from a graphics tablet, comprising successive x, y co-ordinate positions. The digital data is encoded (e.g. using x, y encoding) into a series of arbitrary line vectors LV1, LV2, etc and the arbitrary line vectors are subsequently encoded (e.g. using Freeman encoding) into a series of pre-defined line vectors FV1, FV2 etc to afford a character encoded signal. Corresponding ones of the arbitrary line vectors LV1, LV2, etc are compared with the pre-defined line vectors FV1, FV2 etc in order to derive one or more alternative character encoded signals which improve the chances of the character being recognised.</p> |
