Abstract

We present a new method for 2D barcode extraction based on object keypoint selection and line detection for the orientation finding of the barcode. In the interest point detection stage, we apply SURF for fast and robust keypoint detection. Next, we perform a non-linear SVM classification to detect the barcode location. We perform local threshold based on the barcode location in the image before applying a morphological operation to segment the barcode from the background information. Finally, we apply edge detection and Hough Transform to extract information of the barcode content.
