Paper Abstract

During the sonar image acquisition, several physical phenomena degrade the final picture a lot. We examine particularly two damages: the energy loss function of the distance covered by the acoustical wave and the speckle noise. For the first phenomenon, we suggest a corrective post processing which takes some acquisition parameters into account. For the second phenomenon, we apply filtering algorithms like the maximum a posteriori filter, a modified version of the Lee algorithm or an adaptive weighted median filter. The results are shown on real sonar images.
