DOI: 10.1109/lsp.2022.3143038
Abstract: Data hiding in encrypted images (DHEI) embeds data in the cipher state, which not only protects the confidentiality of the cover image content, but also hides the existence of the secret information, and has a… read more here.

DOI: 10.1109/tac.2018.2835380
Abstract: In this paper, we consider the identification of matrix state-space models (MSSM) of the following form: \begin{align*} \mathbf {X}(k+1) &= \mathbf {A}_2 \mathbf {X}(k) \mathbf {A}_1^T + \mathbf {B}_2 \mathbf {U}(k) \mathbf {B}_1^T \\ \mathbf… read more here.

DOI: 10.1190/geo2019-0254.1
Abstract: Least-squares reverse time migration (LSRTM) has become increasingly popular for complex wavefield imaging due to its ability to equalize image amplitudes, attenuate migration artifacts, handle incomplete and noisy data, and improve spatial resolution. The major… read more here.
