The invariants are defined in Fourier spectral domain by means of projection operators and, equivalently, in the image domain by means of image moments. The application of these invariants is in blur-invariant image comparison and recognition. The behavior of the invariants is studied and compared with other methods in experiments on both artificial and real blurred and noisy images. cav_un_auth*0319307 Computer Analysis of Images and Patterns Valletta 02.09.2015-04.09.2015 MT 2016 IN PO RVO:67985556 http://hdl.handle.net/11104/0249422 S 0.329 Q2 Q2 2015 84945913608 SCOPUS 000364705500008 WOS cav_un_epca*0447047 Computer Analysis of Images and Patterns - CAIP 2015 I 978-3-319-23192-1 0302-9743 88 99 Computer Analysis of Images and Patterns - CAIP 2015 Switzerland Springer International Publishing 2015 Lecture Notes in Computer Science 9256 Azzopardi George 340 Petkov Nicolai 340
