This sequence illustrates the ability of the method to ignore parasitical data on the presented diagnostic sequence.
It involves a static background and a layer corresponding to the diaphragm and the lungs. A guide wire is also present.
The estimated displacements are directed toward the past to respect the notations of the Transparent Motion Constraint.
As a result they are in the opposite direction compared to the usual represented velocity direction.
Estimation result at two interesting time instants
The first presented motion estimation shows that the method has successfully ignored the parasitical motion of the guide wire.
The second presented motion estimation shows that the motion of the guide wire is correctly estimated when it is smooth
enough to follow a parametric model.
Whole processed sequence
We also present the overall processed sequence. It shows the estimated affine motion fields, along with the corresponding
frames.
The results are satisfactory for about 95% of time instants, though the presence of the guide wire and of a contrast injection!
