Lorentz violation, Gravity, Dissipation and Holography [PDF]

open access: yes, 2012
We reconsider Lorentz Violation (LV) at the fundamental level. We show that Lorentz Violation is intimately connected with gravity and that LV couplings in QFT must always be fields in a gravitational sector.

Parallelizing Scale Invariant Feature Transform on a Distributed Memory Cluster [PDF]

open access: yes, 2011
Scale Invariant Feature Transform (SIFT) is a computer vision algorithm that is widely-used to extract features from images. We explored accelerating an existing implementation of this algorithm with message passing in order to analyze large data sets ...

Robust Descriptor Algorithm Considering the Changing Gray Value Trends Inside Ground Objects for Heterogeneous Optical Image Matching

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Differences in sensor types, resolutions, and imaging conditions can lead to considerable spectral differences in heterogeneous optical remote sensing images and the similarity of scale-invariant feature transform (SIFT) or local self-similarities (LSS ...
