DOI: 10.1109/lgrs.2022.3216638
Abstract: This letter presents a multitarget tracking algorithm—thresholded sequential Monte Carlo probability hypothesis density (TH-SMC-PHD) algorithm. The TH-SMC-PHD aims to overcome the problem that underwater multitarget tracking is prone to missing tracking on sonar images, resulting… read more here.

DOI: 10.1109/tgrs.2022.3211847
Abstract: This work solves the long-tail and few-shot (LTFS) problems faced concurrently in sonar image classification. Although the popular deep transfer learning (TL) alleviates the few-shot problems, it performs poorly in the tail classes. Moreover, current… read more here.
