Extraction of the Pulse Wave Envelope and the Feature Points Tracking

XIA Jun;TAO Hongfeng;Key Laboratory of Advanced Process Control for Light Industry,Ministry of Education,Jiangnan University;  
This paper proposes a new algorithm to extract the pulse wave envelope and to track its feature points.Firstly,we cut the ROI area of the image,using the otsu method to binary the image. Further more,combining with morphological operators and sobel operators detects the pulse wave envelope,and using a multi-threshold method locates the feature points of the pulse wave images.
