DOI: 10.1080/2150704x.2016.1268731

Abstract: ABSTRACT Phase filtering is an important processing step in interferometric synthetic aperture radar (InSAR) measurement. It is a difficult task to achieve noise reduction and fringe preservation simultaneously. To solve the dilemma, a new noise… read more here.

DOI: 10.1109/access.2024.3357835

Abstract: The Total Generalized Variation (TGV) model proves effective in removing texture and background patterns in natural images while suppressing the staircase effect introduced by traditional Total Variation (TV) regularization. Nevertheless, TGV falls short in preserving… read more here.

recommendations! Published in 2019 at "IEEE Sensors Journal"

DOI: 10.1109/jsen.2019.2926232

Abstract: Image reconstruction in electrical impedance tomography is an ill-posed inverse problem. To address this problem, regularization methods such as Tikhonov regularization and total variation regularization have been adopted. However, the image is over-smoothed when reconstructing… read more here.

DOI: 10.1109/lgrs.2020.3043435

Abstract: Pansharpening can be regarded as an inverse problem, where a high-resolution multispectral (MS) image is estimated given a low-resolution MS image and a panchromatic (Pan) image. Considering the effectiveness of total generalized variation (TGV) to… read more here.

DOI: 10.1117/1.jei.26.5.053021

Abstract: Abstract. Image deblurring is one of the classical problems in image processing and computer vision. The vital task is to restore the high-quality image with edge-preservation, details-protection, and artifacts suppression. In order to achieve ideal… read more here.
