Compressive stresses play important roles on tumor cells proliferation and invasion. In this work we propose to inform a tumor growth model with the recovered deformation coming from in vivo imaging data. We investigated the use of an optical flow technique, the well known Lucas-Kanade method, to capture tumor deformation in a synthetic experimental breast cancer setting. We compare displacements and stresses obtained with this method with those derived from a previously developed reaction-diffusion model with mechanical deformation. We show that the considered optical flow technique may capture deformations appearing in breast cancers, being a useful alternative to integrate in vivo data to mathematical tumor models.
