In this letter, an adaptive gradient search algorithm for displaced subarray optimization is presented. The displaced subarray technique, which is able to suppress the high grating lobes caused by ...

In this paper, we present a novel gradient-based algorithm for adapting a multichannel FIR filter bank under channel orthogonality and magnitude response constraints. The technique is the multichannel ...

Researchers at the University of Tokyo developed ADOPT, a novel optimization algorithm that overcomes convergence issues in adaptive gradient methods, promising more reliable and efficient ...

Methods: In this article, an image structure adaptive gradient vector flow (ISAGVF) external force is proposed for active contours. In the proposed ISAGVF model, the smoothness constraint is first ...
