DOI: 10.1109/tccn.2025.3573701
Abstract: Quantization-based graph transform (QGT) provides a unique perspective on spectrum sensing in cognitive radio networks. Conventional QGT-based spectrum sensing algorithms leverage the topological characteristics of the graph derived from observed signals. However, they often exhibit… read more here.

DOI: 10.1109/tip.2021.3134466
Abstract: Reversible visible watermarking (RVW) is an active copyright protection mechanism. It not only transparently superimposes copyright patterns on specific positions of digital images or video frames to declare the copyright ownership information, but also completely… read more here.

DOI: 10.1109/tsp.2018.2870386
Abstract: In this paper, we present a novel generalization of the graph Fourier transform (GFT). Our approach is based on separately considering the definitions of signal energy and signal variation, leading to several possible orthonormal GFTs.… read more here.

DOI: 10.3389/fnins.2022.867466
Abstract: Electrophysiological source imaging (ESI) refers to the process of reconstructing underlying activated sources on the cortex given the brain signal measured by Electroencephalography (EEG) or Magnetoencephalography (MEG). Due to the ill-posed nature of ESI, solving… read more here.
