Posterior Mean Super-Resolution with a Compound Gaussian Markov Random Field Prior

, 2012
This manuscript proposes a posterior mean (PM) super-resolution (SR) method with a compound Gaussian Markov random field (MRF) prior. SR is a technique to estimate a spatially high-resolution image from observed multiple low-resolution images. A compound

Bayesian Reconstruction of Missing Observations [PDF]

, 2015
We focus on an interpolation method referred to Bayesian reconstruction in this paper. Whereas in standard interpolation methods missing data are interpolated deterministically, in Bayesian reconstruction, missing data are interpolated probabilistically ...

Light‐Driven Competitive Selection in a Protein‐Catalyzed Dissipative Peptide Replication

Angewandte Chemie, EarlyView.
A structurally flexible protein catalyzes replication within a dissipative reaction network driven by UVA‐induced disulfide rearrangements. The protein accelerates templated autocatalytic cycles with replication emerging as the dominant pathway.

Probabilistic ToF and Stereo Data Fusion Based on Mixed Pixel Measurement Models [PDF]

, 2015
This paper proposes a method for fusing data acquired by a ToF camera and a stereo pair based on a model for depth measurement by ToF cameras which accounts also for depth discontinuity artifacts due to the mixed pixel effect.
