Abstract
In the paper a problem of displacement calculation of the walls of left heart ventricle in echocardiographic (ECG) ultrasound sequences/videos is addressed. A novel method, which is proposed in it, consists of: 1) speckle reduction anisotrophic diffusion (SRAD) filtration of ultrasonography (USG) images, 2) segmentation of heart structures in consecutive de-noised frames via active contour without edges method, 3) calculation of left ventricle frame-to-frame deformation vectors by B-Spline Free Form Deformation (FFD) algorithm. Results from method testing on synthetic USG-like and real ECG images are presented in the paper.
