Globally Optimal Rigid Intensity Based Registration: A Fast Fourier Domain Approach

no code implementations CVPR 2016 Behrooz Nasihatkon, Frida Fejne, Fredrik Kahl

In this paper, we propose a dual algorithm in which the optimization is done in the Fourier domain, and multiple resolution levels are replaced by multiple frequency bands.

Multiresolution Search of the Rigid Motion Space for Intensity Based Registration

no code implementations14 Oct 2015 Behrooz Nasihatkon, Fredrik Kahl

Our results show that low resolution target values can tightly bound the high-resolution target function in natural images.

On Projective Reconstruction In Arbitrary Dimensions

no code implementations CVPR 2014 Behrooz Nasihatkon, Richard Hartley, Jochen Trumpf

The current theory, due to Hartley and Schaffalitzky, is based on the Grassmann tensor, generalizing the ideas of fundamental matrix, trifocal tensor and quadrifocal tensor used in the well-studied case of 3D to 2D projections.
