Abstract
Ultrasound waves are preferably used as means to provide details about the inner structure of materials, thus providing a way to non-destructively evaluate the quality of produced components. Nevertheless, ultrasonic data are strongly a ected by a multiplicative type of noise referred to as speckle noise. Within this paper, the modeling of the intensity distribution within ultrasound imagesand volumetric data is addressed through parametric approach modeling. The proposed model was compared with the state of the art models through measuring the corresponding goodness of fit of eachmodel to the actual data distribution. The data were acquired on aluminum, ceramic and composite structures.
