Abstract :
Texture analysis is performed on multibeam sonar imagery. A set of 14 texture features is computed using cooccurrence matrices to form the feature space. The dimensionality of the feature space is reduced by extracting the principal components from the original feature space. Classification of the image is performed on the principal components using the K-means algorithm. Results indicate that seafloor bottom types can be characterized by analyzing the texture of bathymetric sonar images
