Abstract
A processing method for a color barcode image captured by a camera or barcode reader. The barcode includes color data cells and multiple large black locators which are located at the four corners of the barcode, along the four borders, and inside the barcode forming an array. The locators are first identified from a grayscale version of the barcode image using multiple binarization technique to ensure that all locators are identified. Perspective correction and illumination correction may be applied to the barcode image using the identified locators.
