Coherent actions by homeomorphisms on the real line or an interval
We study actions of groups by orientation preserving homeomorphisms on R (or an interval) that are minimal, have solvable germs at +/-infinity and contain a pair of elements of a certain dynamical type. We call such actions coherent. We establish that such ...
HEBREW UNIV MAGNES PRESS2020Approximating nonabelian free groups by groups of homeomorphisms of the real line
We show that for a large class C of finitely generated groups of orientation preserving homeomorphisms of the real line, the following holds: Given a group G of rank k in C, there is a sequence of k-markings (G,S-n), n is an element of N whose limit in the ...
2020The index of singular zeros of harmonic mappings of anti-analytic degree one
We study harmonic mappings of the form , where h is an analytic function. In particular, we are interested in the index (a generalized multiplicity) of the zeros of such functions. Outside the critical set of f, where the Jacobian of f is non-vanishing, it ...
TAYLOR & FRANCIS LTD2019Method, system, and device for learned invariant feature transform for computer images
Pascal Fua, Vincent Lepetit, Kwang Moo Yi, Eduard Trulls Fortuny
A method for training a feature detector of an image processing device, including the steps of detecting features in the image to generate a score map, computing a center of mass on the score map to generate a location, extracting a patch from the image at ...
