Parametrização de Campo Bidimensional de Velocidades Sísmicas Usando Ondaletas

The aim of this work is the representation (parameterization) of compressional seismic velocity field model of two dimensional geological structure by means of orthogonal functions known as wavelets more specifically, those so-called Haar wavelet. Some<br>comparative numerical experiments are performed among wavelet series with and without the use of scale function. The velocity field approximation, obtained by such technique, depends on the indices values used in the series, these have influence on the quality of the model representation. It is observed that the proposed parameterization offers a good accuracy for representation of the used field, however it is just advantageous the use of the scale function in the wavelet series with lower indices values.
