其他摘要：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.
