Original Abstract

This contribution refers to the fusion of 2D multi-spectral images. Short review of the currently used methods is given and an algorithm using the wavelet representation of vector-valued is discussed. The pyramidal dyadic wavelet transform is modified according to the definition of maximal length of the multi-valued gradient and a solution of problems with orientation of the computed orthogonalized gradient is given. Several applications of the method including multimodal ophtalmic images fusion and multi-focused color photographs creation are presented and the suitability of the fusion for subsequent processing is discussed.

Tento příspěvek pojednává o fúzi 2D vícespektrálních obrazů. Jsou krátce shrnuty současné metody obrazové fúze, přičemž algoritmus využívající vlnkové reprezentace vektorových dat je probrán detailněji. Tento algoritmus modifikuje pyramidální dyadickou vlnkovou transformaci pomocí definice maximální délky gradientu vektorového obrazu. Jsou popsány aplikace metody pro fúzi multimodálních oftalmologických obrazů a obrazů zaostřených do různých ohnisek.
