Identification of piecewise constant sources in non-homogeneous media based on boundary measurements

Boundary Detection in Piecewise Homogeneous Textured Images

1 I n t r o d u c t i o n The problem of texture analysis (recognition and segmentation) has traditionally been approached by computing locally defined vector-valued "descriptors" of each region in the image. The texture recognition problem is thus reduced to a conventional classification problem, and boundary detection may be performed by locating areas of rapid change in the descriptor vector...

Online allocation and homogeneous partitioning for piecewise constant mean-approximation

In the setting of active learning for the multi-armed bandit, where the goal of a learner is to estimate with equal precision the mean of a finite number of arms, recent results show that it is possible to derive strategies based on finite-time confidence bounds that are competitive with the best possible strategy. We here consider an extension of this problem to the case when the arms are the ...

Piecewise Constant Aquifer Parameter Identification Recovery

For many inverse problems which arise in contributing to real-world decision-making, such as formulating policy objectives for freshwater fish health, only an indicative understanding of the global structure of the solution is all that is required for the associated decision-support. Examples include: (i) Situations where only some linear functional of the solution is required. As noted in vari...
