Synthetic ground-truth data for speckle tracking algorithms

This folder contains data and code accompanying the paper [1]. The database is composed of 105 simulated sequences, including:

<ul>
<li> simulated texture from 7 vendors; </li>
<ul>
<li> 5 motion patterns;</li>
<li> 3 probe orientations;</li>
</ul>
</ul>

<ul>
<li> For each sequence we provide: </li>
<ul>
<li> simulated B-mode data: path = "./data <vendor_id>/<view_id>/<motion_id>/im_sim.mat";</li>
<li> ground truth tracking: path = "./data/<vendor_id>/<view_id>/ <motion_id>/ground_truth.mat";</li>
</ul>
</ul>

The following MATLAB scripts are provided to facilitate the use of the data:
<ul>
<li> main_play_data.m: to play the simulated cine-loops as well as the ground truth tracking;</li>
<li> main_compute_strain.m: to compute ground truth segmental strain.</li>
</ul>
