Hyperspectral Image Unmixing via Alternating Projected Subgradients
Hyperspectral Image Unmixing Alternating Projected Subgradients
2015/7/10
We formulate the problem of hyperspectral image unmixing as a nonconvex optimization problem, similar to nonnegative matrix factorization. We present a heuristic for approximately solving this problem...
Optimal Estimation of Deterioration from Diagnostic Image Sequence
Damage interior-point methods optimal estimation regularization
2015/7/9
Estimation of mechanical structure damage can greatly benefit from the knowledge that the damage accumulates irreversibly over time. This paper formulates a problem of estimation of a pixel-wise monot...
Variational Bayesian Image Restoration Based on a Product of t-Distributions Image Prior
product prior Student’s-t prior
2015/7/3
Image priors based on products have been recognized
to offer many advantages because they allow simultaneous enforcement of multiple constraints. However, they are inconvenient for
Bayesian inferenc...
