Sifting Convolution on the Sphere [PDF]
IEEE Signal Processing Letters, vol. 28, pp. 304-308, 2021, 2020 A novel spherical convolution is defined through the sifting property of the Dirac delta on the sphere. The so-called sifting convolution is defined by the inner product of one function with a translated version of another, but with the adoption of an alternative translation operator on the sphere.

Stratified SIFT Matching for Human Iris Recognition [PDF]
Proceedings of International Conference on Advances in Computing
and Communications (ACC-2011), 2013 This paper proposes an efficient three fold stratified SIFT matching for iris recognition. The objective is to filter wrongly paired conventional SIFT matches. In Strata I, the keypoints from gallery and probe iris images are paired using traditional SIFT approach. Due to high image similarity at different regions of iris there may be some impairments.

Proceedings of the International Florida Artificial Intelligence Research Society Conference, 2023 ARCHIMEDES is a suite of algorithms for planning and task allocation to monitor and surveil a geometrically defined area with a group of heterogenous agents. We focus on maximizing the information gained over a fleet of such agents.

SAR-SIFT: A SIFT-Like Algorithm for SAR Images [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2015 The scale-invariant feature transform (SIFT) algorithm and its many variants are widely used in computer vision and in remote sensing to match features between images or to localize and recognize objects. However, mostly because of speckle noise, it does not perform well on synthetic aperture radar (SAR) images.
