【摘要】 舌背区域自动撷取算法是为了获得舌下络脉特征所在的焦点区域,对于舌下络脉诊断自动的实现具有重要意义。采用基于形态学标记的水域分割算法大致确定了舌背所在区域,藉由分析舌背和剩余的背景彩色分量的差异性进行后处理。实验结果表明,该算法所撷取的舌背区域效果良好,健壮性好。此结果为实现后续舌下络脉特征分析奠定了基础。更多还原

【Abstract】 The automatic acquisition of tongue back is important to sublingual veins diagnosis.Using watershed segmentation algorithm based on morphology marker can largely locate the area including the back of tongue.By analyzing color components difference between the back of tongue and rest background can finally extract the back of tongue.Experimental results show that the algorithm works well,good robustness.The results lay the good foundation for follow-up features analysis of sublingual veins.更多还原
