Improper Gaussian Signaling for the $K$-user MIMO Interference Channels with Hardware Impairments

no code implementations28 Jan 2020 Mohammad Soleymani, Ignacio Santamaria, Peter J. Schreier

This paper investigates the performance of improper Gaussian signaling (IGS) for the $K$-user multiple-input, multiple-output (MIMO) interference channel (IC) with hardware impairments (HWI).

Two-Channel Passive Detection Exploiting Cyclostationarity

1 code implementation17 Jun 2019 Stefanie Horstmann, David Ramírez, Peter J. Schreier

This paper addresses a two-channel passive detection problem exploiting cyclostationarity.

Deep Morphing: Detecting bone structures in fluoroscopic X-ray images with prior knowledge

no code implementations9 Aug 2018 Aaron Pries, Peter J. Schreier, Artur Lamm, Stefan Pede, Jürgen Schmidt

We propose approaches based on deep learning to localize objects in images when only a small training dataset is available and the images have low quality.

Model-order selection in statistical shape models

1 code implementation1 Aug 2018 Alma Eguizabal, Peter J. Schreier, David Ramírez

It requires choosing a model order, which determines how much of the variation seen in the training data is accounted for by the PDM.

A weighting strategy for Active Shape Models

no code implementations28 Jul 2017 Alma Eguizabal, Peter J. Schreier

Finding these targets is a critical step: some landmarks are more reliably detected than others, and some landmarks may not be within the field of view of their detectors.

Detecting Directionality in Random Fields Using the Monogenic Signal

no code implementations10 Apr 2013 Sofia Olhede, David Ramírez, Peter J. Schreier

Classifying a structure as directional or non-directional requires a measure to quantify the degree of directionality and a threshold, which needs to be chosen based on the statistics of the image.
