Abstract
A camera-based barcode reader captures an image, determines a region of interest of a barcode within the image, and generates a barcode image from the region of interest. The camera-based barcode reader aligns each of multiple horizontal regions within the barcode image to a reference horizontal region within the barcode image. The alignment of a horizontal region includes (i) determining a set of alignment parameters to apply to the horizontal region based on a comparison of the reference horizontal region to the horizontal region when adjusted to different combinations of alignment parameters and (ii) adjusting the horizontal region according to the set of alignment parameters for that horizontal region. After aligning the barcode image, the camera-based barcode reader decodes the barcode from the barcode image.
