Exploring mutual information between IRIS spectral lines. I. Correlations between spectral lines during solar flares and within the quiet Sun
Brandon Panos, Lucia Kleint, Sviatoslav Voloshynovskiy
Spectral lines allow us to probe the thermodynamics of the solar atmosphere, but the shape of a single spectral line may be similar for different thermodynamic solutions. Multiline…
Solar activity classification based on Mg II spectra: towards classification on compressed data
Sergey Ivanov, Maksym Tsizh, Denis Ullmann +2
Although large volumes of solar data are available for study, the vast majority of these data remain unlabeled and are therefore not amenable to supervised machine learning methods…
Identifying typical Mg II flare spectra using machine learning
B. Panos, L. Kleint, C. Huwyler +4
IRIS performs solar observations over a large range of atmospheric heights, including the chromosphere where the majority of flare energy is dissipated. The strong Mg II h&k spectr…
Sparse Multi-layer Image Approximation: Facial Image Compression
Sohrab Ferdowsi, Svyatoslav Voloshynovskiy, Dimche Kostadinov
We propose a scheme for multi-layer representation of images. The problem is first treated from an information-theoretic viewpoint where we analyze the behavior of different source…
Multi-layer Architecture For Storing Visual Data Based on WCF and Microsoft SQL Server Database
Rafal Grycuk, Marcin Gabryel, Rafal Scherer +1
In this paper we present a novel architecture for storing visual data. Effective storing, browsing and searching collections of images is one of the most important challenges of co…
Fast Dictionary Matching for Content-based Image Retrieval
Patryk Najgebauer, Janusz Rygal, Tomasz Nowak +4
This paper describes a method for searching for common sets of descriptors between collections of images. The presented method operates on local interest keypoints, which are gener…
Information Theoretical Analysis of Identification based on Active Content Fingerprinting
Farzad Farhadzadeh, Frans M. J. Willems, Sviatoslav Voloshinovskiy
Content fingerprinting and digital watermarking are techniques that are used for content protection and distribution monitoring. Over the past few years, both techniques have been…
