1. A method of performing character isolation in an optical character recognition process, the method comprising:

  • receiving image data representing one or more character columns;

    determining a number of black pixels in each column of the image data;

    defining a vertical separation threshold which is a maximum number of black pixels in a column;

    dividing the columns into different pixel groups and groups of excluded columns by excluding any columns with a number of black pixels below the vertical separation threshold;

    identifying the pixel group representing the left most character column in the image data;

    determining whether there are one or two pixel groups representing character columns in the image data; and

    if it is determined that there are two pixel groups representing character columns, using a predetermined width value for a right most character column in order to identify a right hand boundary of the right most character column.
