A focus measure for light field rendering
Light field rendering is a fundamental method for synthesizing free-viewpoint images from a set of multi-viewpoint images. In the simplest case, the scene structure is approximate...

Norm, Point, and Distance Estimation Over Multiple Signals Using Max-Stable Distributions
Consider a set of signals fs : {1, . . . , N} [0, . . . , M] appearing as a stream of tuples (i, fs(i)) in arbitrary order of i and s. We would like to devise one pass approximat...
