Abstract: A recognition method and apparatus is disclosed which provides information on what type of barcode is to be recognized and the strategy to be applied in identifying and decoding the barcode. For N raster lines of a dimension "x", an array of one byte sums of dimension "x" is created. The sums are the sum of the "1" bits in the rectangular binary image input array in the N lines of the image. A new array can be generated which will have a dimension equal to the number of changes from black to white in the original "x-y" digital image. The values in this array will represent the length of each run of same color pels. These runs are then normalized according to rules of a particular barcode standard being handled.
