Quasi-spectral characterization of intracellular regions in bright-field light microscopy images
Kirill Lonhus, Renata Rychtarikova, Ganna Platonova +1
Investigation of cell structure is hardly imaginable without bright-field microscopy. Numerous modifications such as depth-wise scanning or videoenhancement make this method being…
Segmentation of laterally symmetric overlapping objects: application to images of collective animal behaviour
K. Lonhus, D. Štys, M. Saberioon +1
Video analysis is currently the main non-intrusive method for the study of collective behavior. However, 3D-to-2D projection leads to overlapping of observed objects. The situation…
Point Divergence Gain and Multidimensional Data Sequences Analysis
Renata Rychtáriková, Jan Korbel, Petr Macháček +1
We introduce novel information-entropic variables -- a Point Divergence Gain (), a Point Divergence Gain Entropy (), and a Point Divergence Gain Entro…
Colorimetric Calibration of a Digital Camera
Renata Rychtarikova, Pavel Soucek, Dalibor Stys
In this paper, we introduce a novel - physico-chemical - approach for calibration of a digital camera chip. This approach utilizes results of measurement of incident light spectra…
Optimal noise in the hodgepodge machine simulation of the Belousov-Zhabotinsky reaction
Dalibor Stys, Krystof M. Stys, Anna Zhyrova +1
One of the simplest multilevel cellular automata - the hodgepodge machine - was modified to best match the chemical trajectory observed in the Belousov-Zhabotinsky reaction. Noise…
