Abstract: Abstract: A novel method for fast reading barcodes commonly
encountered in industrial applications is presented. The method
mainly consists of two stages: (1) a process characterizing in
cross scanning an overly downscaled image to extract candidate
barcode skeletons is used to locate barcodes in an image,
wherein at least one skeleton is extracted from the downscaled
binary image; coordinates of at least one point of each skeleton
are enlarged back to their original resolution and used as center
points of plural detection windows in the original image plane. (2)
a Sobel-based grading scheme is employed to determine wining
detection windows for reading barcodes, wherein a retrospective
tracking mechanism is proposed to deal with warped, slanted or
even stained barcodes. Since the center points of the wining
detection windows are directly treated as sampling points of the
barcodes, pixel by pixel search is dispensable and computation
time can be greatly reduced.
