3D filtry a jejich použití v počítačovém modelování

3-D filters and their use for computer modelling

conference paper

en

The paper presents an interesting generalisation of 2-D filters known in image processing. The filters presented in this paper can be used to 3-D objects processing with analogous effects to 2-D ones. Several attributes can be assigned to each voxel in the processing 3-D object (space co-ordinates, colour, transparency, potential e.t.c.). Each of these attributes can be filtered. These filters can be used to surface smoothing, erosive filters delete small 3-D objects. The high-pass 3-D filters detect object surfaces, draw power field isosurfaces e.t.c. Topographical and biological applications are demonstrated.

V článku je prezentováno zajímavé zobecnění obrazových filtrů známých z obrazové analýzy. Vícerozměrné filtry mají alalogické vlastnosti a umožńují efektivně modelovat prostorové objekty.
