DOI: 10.1007/s00530-020-00749-3
Abstract: Digital videos are an incredibly important source of information, and as evidence, they are highly inculpatory. Digital videos are also inherently prone to conscious semantic manipulations, such as copy–paste forgeries, which involve insertion or removal… read more here.

DOI: 10.1016/j.neucom.2019.10.054
Abstract: Abstract Existing fixed pattern noise reduction (FPNR) methods are easily affected by the motion state of the scene and working condition of the image sensor, which leads to over smooth effects, ghosting artifacts as well… read more here.

DOI: 10.1016/j.optlaseng.2020.106461
Abstract: Abstract Digital holography allows registering and reconstructing information about 3D objects and 3D scenes. There are several limitations related to reconstructed image quality: speckle noise, twin images, zero order, light (shot noise) and dark temporal… read more here.

DOI: 10.1109/access.2021.3109561
Abstract: A reference-free image index to jointly assess infrared-imaging fixed-pattern-noise and blur artifacts is proposed in this work. The proposed index is based on tuned-spatial-domain filtering, which works by combining two Laplace operators to simultaneously quantify… read more here.
