Sonar Image Preprocessing Method based on Homomorphic Filtering
Résumé
This paper is concerned with the problem of preprocessing
Synthetic Aperture Sonar (SAS) images.
Considering its proprieties, this paper proposes to perform the homomorphic filter on the sonar images, corrupted by speckle. Moreover, robust criteria are defined to evaluate the proposed filtering. The statistic modelling of sonar image is then used to evaluate the contribution of the filtering method
in the detection step.
