| Abstract: | Based on the histogram resampling,the rational threshold was determined by means of histogram fitting to implement the digital seal＇s binary segmentation.Utilizing mathematical morphology operators,the binary seal image was enhanced with burr eliminating.With the clipping algorithm,the skeleton of the digital seal was extracted from the thinning image.After such processing mentioned,the chain-code was encoded. |
