Segmentation of Bar Code Image with Complex Background Based on Template Matching
Pan Shuguo · Journal of Hehai University Changzhou · 2003
This paper deals with the application of image segmentation to the automatic identification of a bar code image with a complex background. At first,image erosion of the background such as characters is pre-processed, yielding isolated points, which are filtered by a median filter. The relative position of the bar code does not change. Then using template matching,the bar code region can be segmented. As there is no universal methods and specifications in image segmentation,the bar code identification software is used to judge the segmenting effect.
