摘要：A method of performing character isolation in an optical character recognitionprocess, the method comprising receiving image data representing one or morecharacter 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 pixelsin a column, dividing the columns into different pixel groups and groups of excludedcolumns by excluding any columns with a number of black pixels below the verticalseparation threshold, identifying the pixel group representing the left most charactercolumn in the image data, determining whether there are one or two pixel groupsrepresenting character columns in the image data and, if it is determined that there aretwo pixel groups representing character columns, using a predetermined width value fora right most character column in order to identify a right hand boundary of the rightmost character column.
