| dc.description.abstract-translated | Information in images (as well as in volume data or video) is typically represented by an array of pixels, where each pixel stores either greyscale luminance or colour components values. Due to the simplicity of this representation, many algorithms from signal processing can be implemented efficiently with ease. For some applications, however, this representation may not be the best one as it is quite space consuming (although the storage requirements can be reduced by using image compression techniques such as JPEG) and is liable to the occurrence of aliasing artefacts. This thesis describes possibilities of alternative representation of image information based on the exploitation of various geometrical data structures such as triangulations (e.g., Delaunay triangulation), etc. It investigates various methods for the evaluation of the significance of pixels and it deals with the problem how to reconstruct image data from significant pixels only. Various methods for the storing of significant pixels in compact forms are also discussed. Methods proposed in this thesis are compared with already existing meth ods. The thesis also describes the possible extension for video and discusses the options of direct manipulation with images represented by triangulations. | en |
