SAR moving target imaging using group sparsity [PDF]

open access: yes, 2013
SAR imaging of scenes containing moving targets results in defocusing in the reconstructed images if the SAR observation model used in imaging does not take the motion into account.

Video foreground detection based on symmetric alpha-stable mixture models. [PDF]

open access: yes, 2010
Background subtraction (BS) is an efficient technique for detecting moving objects in video sequences. A simple BS process involves building a model of the background and extracting regions of the foreground (moving objects) with the assumptions that the

A ViSAR Shadow-Detection Algorithm Based on LRSD Combined Trajectory Region Extraction

open access: yesRemote Sensing, 2023
Shadow detection is a new method for video synthetic aperture radar moving target indication (ViSAR-GMTI). The shadow formed by the target occlusion will reflect its real position, preventing the defocusing or offset of the moving target from making it ...

Improvement Algorithm of ViBe in Moving Target Detection

open access: yesJournal of Harbin University of Science and Technology, 2022
Aiming at the problem that Visual Background Extractor(ViBe) algorithm is not sensitive to light mutation and is mistakenly detected as foreground due to a large number of high-frequency disturbed objects in the background, an improved method is proposed
