The Algebraic Structure of the KLT Relations for Gauge and …
2021年11月14日 · We study the Kawai-Lewellen-Tye (KLT) relations for quantum field theory by reformulating it as an isomorphism between two Lie algebras. We also show how explicit formulas for KLT relations arise when studying rational functions on M0,n, and prove identities that allow for arbitrary rational functions to be expanded in any given basis.
Title: Generalizations of the Double-Copy: the KLT Bootstrap
2021年6月23日 · We formulate a new program to generalize the double-copy of tree amplitudes. The approach exploits the link between the identity element of the KLT algebra and the KLT kernel, and we demonstrate how this leads to a set of KLT bootstrap equations that the double-copy kernel has to satisfy (in addition to locality constraints).
Parametric analysis of KLT algorithm in autonomous driving
The Kanade-Lucas-Tomasi(KLT) tracking algorithm is a widely used feature tracking algorithm in the field of computer vision(CV). The selection of proper warping parameters for the estimation of optical flow between adjacent image frames is crucial to …
Pairwise KLT-Based Compression for Multispectral Images
2016年1月21日 · In this paper, we investigate in depth the KLT-based approach, and we propose an efficient algorithm based on pairwise KLT, which employs pairwise-KLT for spectral decorrelation and DWT for spatial decorrelation with proper rate allocation, followed by embedded block coding with optimized truncation (EBCOT) coding scheme.
Fast gain-adaptive KLT tracking on the GPU - Semantic Scholar
2008年6月23日 · This work presents a refined and substantially accelerated approach to KLT feature tracking performed on the GPU that achieves more than 200 frames per second on state-of-the art consumer GPUs for PAL (720 times 576) resolution data, and delivers real-time performance even on low-end mobile graphics processors.
We construct mildly singular (klt) complex projective varieties with ample canon-ical class and the smallest known volume. We also find exceptional klt Fano varieties with the smallest known volume. In fact, we conjecture that our examples have the minimum volume in every dimension n, and we give low-dimensional evidence to support this.
Direct summands of klt singularities | Inventiones mathematicae
2024年7月22日 · We show that direct summands (or more generally, pure images) of klt type singularities are of klt type. As a consequence, we give a different proof of a recent result of Braun, Greb, Langlois and Moraga that reductive quotients of klt type singularities are of klt type.

GPU-Accelerated KLT Tracking with Monte-Carlo-Based Feature …
In this paper we will demonstrate an alternative feature reselection method that can be efficiently implemented on the GPU. It is a Monte-Carlo-based approximation of the original method and leads to very good tracking results with just a fraction of the computational cost.
Low-complexity rounded KLT approximation for image compression …
2021年10月5日 · In this paper, we introduced a methodology based on the rounding-off function to design low-complexity approximations for the Karhunen–Loève transform (KLT). Due to its relevance in practical image coding systems, the special case \(N …
