摘要
在直方图重采样的基础上,以直方图拟合选取最佳阈值对经灰度化处理的印鉴图像进行二值化分割;进一步对二值化印鉴图像进行基于数学形态学的增强处理;利用修剪算法对细化的印鉴图像进行处理提取其形态学骨架;对印鉴的骨架图像进行了链码编码。
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.
