- Abstract:

In this paper, we present a new vascular characteristics extraction method based on empirical mode decomposition. The proposed method overcomes the problems of noise and the blurred vascular edge generally encountered in the image processing procedure. This method uses empirical mode decomposition to resolve the coronary angiogram into several image layers, retaining the layers that contain blood vessel information and discarding layers that contain only background information. Clear and distinct vessel segments are then extracted from the reserved image layers, based on the connected region’s properties. Finally, the coronary angiogram is reconstructed according to the information extracted from the reserved layers. The experimental results prove that this method has high accuracy and practical medical value.
