In previous works, undecimated wavelet transform was used for affine invariant functions. In this paper, an algorithm based on decimated wavelet transform is developed to compute the affine invariant function. As a result, computational complexity is significantly reduced without decreasing recognition performance. Experimental results are presented.EnglishDyadic wavelet transform (DWT)Wavelet affine invariant functionsAlgorithmsComputational complexityComputer visionFunctionsWavelet transformsObject recognitionConference Paper10.1109/ICIP.2003.1247149
