Locating barcodes using JPEG 2000 compressed data

摘要

In this paper, a novel method is proposed to locate one-dimensional barcodes in JPEG 2000 images. The barcode locating system consists of two parts: candidate barcode location detection, barcode location verification and refinement. Both parts are designed to work in the compressed domain of JPEG 2000 images. The locations of candidate barcodes are extracted from the header data and verified by examining part of the decoded coefficients of the JPEG 2000 file. Since only a small amount of the compressed data is used, this algorithm has a low complexity relative to algorithms which use all of the pixel data.
