It is extremely challenging to binarize 2D barcode image under the condition of both nonuniform illumination and cluttered background. Neither global nor local thresholding method can yield an ideal binary result. In this paper, we propose a novel 2D barcode image binarization method. The contribution of the method is that it can remove the unnormalized… CONTINUE READING
