HARNet: A Convolutional Neural Network for Realized Volatility Forecasting

1 code implementation16 May 2022 Rafael Reisenhofer, Xandro Bayer, Nikolaus Hautsch

HARNets allow for an explicit initialization scheme such that before optimization, a HARNet yields identical predictions as the respective baseline HAR model.

Time Series Analysis

Edge, Ridge, and Blob Detection with Symmetric Molecules

no code implementations28 Jan 2019 Rafael Reisenhofer, Emily J. King

We also show how the behavior of coefficients corresponding to differently scaled and oriented analyzing functions can be used to obtain a comprehensive characterization of the geometry of features in terms of local tangent directions, widths, and heights.

Blind Image Fusion for Hyperspectral Imaging with the Directional Total Variation

2 code implementations4 Oct 2017 Leon Bungert, David A. Coomes, Matthias J. Ehrhardt, Jennifer Rasch, Rafael Reisenhofer, Carola-Bibiane Schönlieb

In this paper, we propose a method for increasing the spatial resolution of a hyperspectral image by fusing it with an image of higher spatial resolution that was obtained with a different imaging modality.

A Haar Wavelet-Based Perceptual Similarity Index for Image Quality Assessment

no code implementations20 Jul 2016 Rafael Reisenhofer, Sebastian Bosse, Gitta Kutyniok, Thomas Wiegand

In most practical situations, the compression or transmission of images and videos creates distortions that will eventually be perceived by a human observer.

Shearlet-Based Detection of Flame Fronts

no code implementations12 Nov 2015 Rafael Reisenhofer, Johannes Kiefer, Emily J. King

Identifying and characterizing flame fronts is the most common task in the computer-assisted analysis of data obtained from imaging techniques such as planar laser-induced fluorescence (PLIF), laser Rayleigh scattering (LRS), or particle imaging velocimetry (PIV).
