Digital Image Steganography Using Bit Flipping

Sahu, Aditya Kumar; Swain, Gandharba; Babu, E. Suresh

2018 Cybernetics and Information Technologies

doi:10.2478/cait-2018-0006

AbstractThis article proposes bit flipping method to conceal secret data in the original image. Here a block consists of 2 pixels and thereby flipping one or two LSBs of the pixels to hide secret information in it. It exists in two variants. Variant-1 and Variant-2 both use 7th and 8th bit of a...

Classification of Mental Tasks from EEG Signals Using Spectral Analysis, PCA and SVM

Neshov, Nikolay N.; Manolova, Agata H.; Draganov, Ivo R.; Tonschev, Krasimir T.; Boumbarov, Ognian L.

2018 Cybernetics and Information Technologies

doi:10.2478/cait-2018-0007

AbstractSignals provided by the ElectroEncephaloGraphy (EEG) are widely used in Brain-Computer Interface (BCI) applications. They can be further analyzed and used for thinking activity recognition. In this paper we proposed an algorithm that is able to recognize five mental tasks using 6 channel...

An Automatically Generated Annotated Corpus for Albanian Named Entity Recognition

Hoxha, Klesti; Baxhaku, Artur

2018 Cybernetics and Information Technologies

doi:10.2478/cait-2018-0009

AbstractNamed Entity Recognition (NER) is an important task in many NLP pipelines. It has become especially important for knowledge bases that power many of the nowadays information retrieval systems. In order to cope with the high demand for annotated training corpora for supervised NER systems,...
