Edge Detection of IVUS Image Based on Active Contour Model and Statistical Features[J]. Journal of Image and Graphics, 2005, 10(8): 999. DOI: 10.11834/jig.200508185.
The edge detection of intravascular ultrasound(IVUS) image has great significance in the diagnosis and treatment of the coronary artery disease. In this paper
a new method used for automatically detecting the intima and adventitia edge of IVUS image is presented.The method bases on active contour model
the contrast and Rayleigh distribution characteristics of IVUS image
effectively uses dynamic programming and heuristic graph searching
and automatically detects the intima and adventitia edge of IVUS image with the different cost functions.Experiments show that
compared with the former method of edge detection
our method is algorithmically simple
statistically accurate
reproducible and robust in sequential IVUS frames
and the algorithm is a kind of global optimal one.
