  6. 5. Implementation and Performance Analysis of Filternets

    University essay from Medicinsk informatik; Tekniska högskolan

    Author : Henrik Einarsson; [2006]
    Keywords : Filter network; sparse filters; efficient filtering; orientation estimation;

    Abstract : Today Image acquisition equipment produces huge amounts of data that needs to be processed. Often the data describes signals with a dimensionality higher then 2, as with ordinary images. This introduce a problem when it comes to process this high dimensional data since ordinary signal processing tools are no longer suitable. READ MORE
