a r t i c l e i n f o a b s t r a c t Motion blur in photographic images is a result of camera movement or shake. Methods such as Blind Deconvolution are used when information about the direction and size of blur is not known. Restoration methods, such as Lucy and Richardson or Wiener reconstruction use information about the direction and size of the blur(More)
The paper has two parts. The rst part presents the theoretical description of modiied method of the coherent optical Fourier transform with a transmission sample, which is placed behind a thin converging spherical optical transform lens and thus illuminated by converging light beam. The second part describes the realized modiied coherent optical-digital(More)
Fe deficiency responses in Strategy I causes a shift from the formation of partially removable hydrous ferric oxide on the root surface to the accumulation of Fe-citrate in the xylem. Iron may accumulate in various chemical forms during its uptake and assimilation in roots. The permanent and transient Fe microenvironments formed during these processes in(More)
Iron(III) oxide shows a polymorphism, characteristic of existence of phases with the same chemical composition but distinct crystal structures and, hence, physical properties. Four crystalline phases of iron(III) oxide have previously been identified: α-Fe2O3 (hematite), β-Fe2O3, γ-Fe2O3 (maghemite), and ε-Fe2O3. All four iron(III) oxide phases easily(More)
Owing to Mössbauer spectroscopy, an advanced characterization technique for iron-containing materials, the present study reveals previously unknown possibilities using l-amino acids for the generation of magnetic particles. Based on our results, a simple choice of the order of l-amino acids addition into a reaction mixture containing ferrous ions leads to(More)
This paper concerns the practical aspects of personal identification based on a statistical analysis of their digitized iris images. Presuming the existence of a database of their numeral representation it is possible to approach the identification process in two ways. If it is a priori known that the tested iris has been already scanned and its(More)
