Resumo


In this work, a comparative analysis between Mexican Hat and Golden Hat wavelets is presented. The latter wavelet belongs to a new family of functions generated from Fibonacci coefficient polynomials. Although these wavelets have a very similar waveform, they have several distinct characteristics in time and the frequency domains. These distinctions are explored here in the scale-space.


Palavras-chave
