Image processing in multiphase polymer systems
Holoubek, Jaroslav
Application of image analysis in the real and inverse space (in the Fourier space) are presented for some multiphase polymer systems. The analysis of the thresholded images of back scattered light from thick polymer material gives information about size and concentration of minor phase domains. Similarly, the phase separation and dissolution processes can be characterized by processing of light scattered patterns detected during time evolution.

Study of supermolecular structure of polymers by light scattering methods
Holoubek, Jaroslav
Various optical techniques, especially light scattering methods, have been investigated as potential candidates for characterization of multiphase polymeric materials, i.e. to measure the size, shape and volume fraction of the minor phase and time evolution of morphology. Some supplementary information has been also obtained from model calculatios of dispersed-phase particles changes, time-resolved light scattering experiments and image analysis.

Application of image analysis in research into geocomposite materials
Ščučka, Jiří
The paper concerns possibilities of the image analysis application to the qualitative and quantitative evaluation of structure and texture of geocomposite materials - the noncohesive rocks injected with polyurethane resins. Understanding the relation between the structure and texture and physical mechanical properties of the materials represents one of the ways, how to determine indirectly probable properties and behaviour of geocomposites formed in practical applications.

Obrazová analýza pohybu struktur uvnitř buněk
Matula, Pe. ; Ondřej, Vladan ; Kozubek, Stanislav
Analysis of time-lapse series of images of living cells requires automation. This contribution concerns the main features of the software package developed for this purpose in our laboratory. Some improvements of our recently published method for tracking of sub-cellular structures based on graph theory are presented. The behaviour of the method is evaluated on images of centromeric heterochromatin defined by HPlbeta-GFP fusion protein. The results show that the method is very well applicable for this type of data.
