Synthetic aperture side-scan sonar (SAS) is an imaging modality for detecting objects on the sea floor and in shallow water. SAS images provide an echo of an object along with its acoustic shadow; both of which can be used in the classification and localization of the object. We developed a Fuzzy C-Means (FCM) image segmentation algorithm that segments the echo of an object and its acoustic shadow in the presence of reverberation noise.
