Abstract
A barcode recognition method and a computer program product thereof are provided. In the barcode recognition method, at first, a foreground extraction step is performed to obtain a binary image of a barcode image. Thereafter, an alignment step is performed to calculate a center coordinate, corner coordinates, a shift vector, and a rotation angle of the target barcode in accordance with the barcode image, the binary image, the shift vector, and the rotation angle. Thereafter, positions of data space patterns, boundary patterns, and an alignment type of the target barcode are determined in accordance with the center coordinate, the corner coordinates, the shift vector, and the rotation angle of the target barcode. Then, values of the target barcode are determined in accordance with the positions of the data space patterns, the boundary patterns, and the alignment type of the target barcode.
