A New Binarization Algorithm for Drug supervision Code Identification
Binarization is an important step in the image processing. Otsu is a kind of typical global threshold method, in the actual image processing, may lost many image details. In order to retain more edge information of the barcode image, a ne? method of adaptive threshold selection is proposed which combines the local threshold with global threshold selection. The experiments show (hat the new binarization algorithm is effective on (he binarization of barcode image and enhance the accuracy of barcode image recognition.
