A Survey of Feature detection methods for localisation of plain sections of Axial Brain Magnetic Resonance Imaging
Jiří Martinů, Jan Novotný, Karel Adámek +3
Matching MRI brain images between patients or mapping patients' MRI slices to the simulated atlas of a brain is key to the automatic registration of MRI of a brain. The ability to…
Cutting the cost of pulsar astronomy: Saving time and energy when searching for binary pulsars using NVIDIA GPUs
Jack White, Karel Adamek, Wes Armour
Using the Fourier Domain Acceleration Search (FDAS) method to search for binary pulsars is a computationally costly process. Next generation radio telescopes will have to perform F…
Averaged Recurrence Quantification Analysis -- Method omitting the recurrence threshold choice
Radim Pánis, Karel Adámek, Norbert Marwan
Recurrence quantification analysis (RQA) is a well established method of nonlinear data analysis. In this work we present a new strategy for an almost parameter-free RQA. The appro…
Bits missing: Finding exotic pulsars using bfloat16 on NVIDIA GPUs
Jack White, Karel Adamek, Jayanta Roy +3
The Fourier Domain Acceleration Search (FDAS) is an effective technique for detecting faint binary pulsars in large radio astronomy datasets. This paper quantifies the sensitivity…
A Novel Greedy Approach To Harmonic Summing Using GPUs
Karel Adamek, Jayanta Roy, Wesley Armour
Incoherent harmonic summing is a technique which is used to improve the sensitivity of Fourier domain search methods. A one dimensional harmonic sum is used in time-domain radio as…
Single Pulse Detection Algorithms for Real-time Fast Radio Burst Searches using GPUs
Karel Adamek, Wesley Armour
The detection of non-repeating or irregular events in time-domain radio astronomy has gained importance over the last decade due to the discovery of fast radio bursts. Existing or…
GPU Fast Convolution via the Overlap-and-Save Method in Shared Memory
Karel Adámek, Sofia Dimoudi, Mike Giles +1
We present an implementation of the overlap-and-save method, a method for the convolution of very long signals with short response functions, which is tailored to GPUs. We have imp…
A GPU implementation of the Correlation Technique for Real-time Fourier Domain Pulsar Acceleration Searches
Sofia Dimoudi, Karel Adamek, Prabu Thiagaraj +3
The study of binary pulsars enables tests of general relativity. Orbital motion in binary systems causes the apparent pulsar spin frequency to drift, reducing the sensitivity of pe…
A polyphase filter for many-core architectures
Karel Adámek, Jan Novotný, Wes Armour
In this article we discuss our implementation of a polyphase filter for real-time data processing in radio astronomy. We describe in detail our implementation of the polyphase filt…
The Implementation of a Real-Time Polyphase Filter
Karel Adámek, Jan Novotný, Wes Armour
In this article we study the suitability of dierent computational accelerators for the task of real-time data processing. The algorithm used for comparison is the polyphase filter,…
