End-to-End Mean Bandwidth Estimation as a Function of Packet Length in Mobile Ad Hoc Networks
Many methods for end-to-end bandwidth estimation on wired networks assume that link capacities are constant and that all cross-traffic interaction occurs through queuing delays at...

Photometric stereo with coherent outlier handling and confidence estimation
In photometric stereo a robust method is required to deal with outliers, such as shadows and non-Lambertian reflections. In this paper we rely on a probabilistic imaging model tha...
