Abstract
Methods based on region matching to estimate velocity field on sequences of 2-D echocardiograms are presented and tested. The method proposed by Singh and Allen (CVGIP: Image Understanding, vol. 56, p. 152-77, 1992) has been modified in the choice of the similarity index. Results of test based on sequences of synthesized images show that template matching methods are more robust and accurate than gradient based methods, while on the other hand computation time is much higher.<>
