recommendations! Published in 2024 at "IEEE Internet of Things Journal"

DOI: 10.1109/jiot.2023.3332867

Abstract: Conventional sparse representation methods cannot effectively characterize the nonlinear effects caused by nonideal space-time factors of multiple-input–multiple-output (MIMO) radar system and scenes with complex nonuniform clutter. In addition, a single dictionary is employed for both… read more here.

DOI: 10.1109/lgrs.2021.3096536

Abstract: Anomalies in remote sensing images are generally reflected in two aspects of spatial and spectral ones, as for the anomaly detection of sea surface using multispectral or hyperspectral images, spectral information is more important. To… read more here.

DOI: 10.1109/tgrs.2023.3264660

Abstract: Seismic wave acquisition is usually disturbed by natural noise and instrument noise. As the seismic wave propagates, the filtering effect of the Earth and its various layers will result in energy attenuation and velocity dispersion;… read more here.

DOI: 10.1364/oe.403317

Abstract: The idea of combining a flexible fiber bundle with the microscopic imaging system provides the possibility of the cross-scale detection of defects and textures on large-scale complex components. However, the pixelization artifacts caused by the… read more here.
