Abstract

We design for this work a new practical tool for computation of non-rigid motion in sequences of 2D heart images. The implementation of our approach allows us to integrate several constraints in the computation of motion: optical flow, matching of different kinds of shape-based landmarks and regularity assumption. Based on the determination of spatio-temporal trajectories, we next propose several measurements to analyze quantitatively the local motion of the left ventricle wall. Some experimental results on cardiac images issued from clinical cases illustrate our approach.
