A Globally Optimal Data-Driven Approach for Image Distortion Estimation
Image alignment in the presence of non-rigid distortions is a challenging task. Typically, this involves estimating the parameters of a dense deformation field that warps a disto...

Local Motion Estimation from Stereo Image Sequences
This paper proposes a method for representing local temporal deformations of a 3D flexible surface in an orthogonal space from a sequence of stereo images. The approach uses a disp...

Correction of Left Ventricle Strain Signals Estimated from Tagged MR Images
Strain measurement is a quantity used for assessing the regional function of the left ventricular (LV) of the heart. They are computed by tracking the motion of the non-invasive, ...

Geometrically Invariant Image Watermarking in the DWT Domain
Watermark resistance to both geometric attacks and lossy compressions is a fundamental issue in the image watermarking community. In this paper, we propose a DWT (Discrete Wavelet ...
