Removing Atmospheric Turbulence Effects in Unified Complex Steerable Pyramid Framework
IEEE Access, 2018 Simultaneously removing atmospheric turbulence-induced geometric distortion and blurry degradation is a challenging task. In this paper, we propose an effective method to remove or at least reduce turbulence effects in unified complex steerable pyramid ...

On two conjectures of Maurer concerning basis graphs of matroids [PDF]
, 2015 We characterize 2-dimensional complexes associated canonically with basis graphs of matroids as simply connected triangle-square complexes satisfying some local conditions. This proves a version of a (disproved) conjecture by Stephen Maurer (Conjecture 3

Rotationally invariant texture features using the dual-tree complex wavelet transform [PDF]
, 2000 New rotationally invariant texture feature extraction methods are introduced that utilise the dual-tree complex wavelet transform (DT-CWT). The complex wavelet transform is a new technique that uses a dual tree of wavelet filters to obtain the real and ...

Patterning nonisometric origami in nematic elastomer sheets [PDF]
, 2018 Nematic elastomers dramatically change their shape in response to diverse stimuli including light and heat. In this paper, we provide a systematic framework for the design of complex three dimensional shapes through the actuation of heterogeneously ...

Genetic stereo matching using complex conjugate wavelet pyramids [PDF]
Proceedings 2001 International Conference on Image Processing (Cat. No.01CH37205), 2002 A new genetic algorithm-based optimisation technique for stereo matching using complex conjugate wavelet pyramids is proposed. Reliable disparity fields are estimated in the wavelet domain with low computational cost. The new cost function is composed of the differences in wavelet coefficient values, plus vertical discontinuity and ordering constraints.

A magic pyramid of supergravities [PDF]
, 2014 By formulating N = 1, 2, 4, 8, D = 3, Yang-Mills with a single Lagrangian and single set of transformation rules, but with fields valued respectively in R,C,H,O, it was recently shown that tensoring left and right multiplets yields a Freudenthal ...

Identifying combinations of tetrahedra into hexahedra: a vertex based strategy
, 2018 Indirect hex-dominant meshing methods rely on the detection of adjacent tetrahedra an algorithm that performs this identification and builds the set of all possible combinations of tetrahedral elements of an input mesh T into hexahedra, prisms, or ...
