A ROBUST METHOD FOR NORMALIZATION OF BARCODE IMAGES SCANNED WITH A MOBILE DEVICE
Abstract
A robust method of normalizing barcode images scanned with a mobile device based on iterative threshold binarization, forming the edge binary image, Hough transform, correction of the angular position of the boundary points and the projective transform is developed. The results of the computer simulation are presented. The method provides the invariance to conditions of printing and lightening (image rotation invariance in the range from -450 to 450, and noninform barcode image illumination invariance) due to using procedures of preprocessing, boundary corner point localization and geometric distortion compensation of the digital barcode images.
