An Efficient Algorithm for Learning-Based Visual Localization
Jindi Zhong, Ziyuan Guo, Hongxia Wang +1
This paper addresses the visual localization problem in Global Positioning System (GPS)-denied environments, where computational resources are often limited. To achieve efficient a…
A novel algorithm for optimizing bundle adjustment in image sequence alignment
Hailin Xu, Hongxia Wang, Huanshui Zhang
The Bundle Adjustment (BA) model is commonly optimized using a nonlinear least squares method, with the Levenberg-Marquardt (L-M) algorithm being a typical choice. However, despite…
Superlinear Optimization Algorithms
Hongxia Wang, Yeming Xu, Ziyuan Guo +1
This paper proposes several novel optimization algorithms for minimizing a nonlinear objective function. The algorithms are enlightened by the optimal state trajectory of an optima…
Optimization Methods Rooting in Optimal Control
Huanshui Zhang, Hongxia Wang
In the paper, we propose solving optimization problems (OPs) and understanding the Newton method from the optimal control view. We propose a new optimization algorithm based on the…
