On Analyzing the Structure of the Seabed

Y. Tan, J. K. Tan, H. Kim and S. Ishikawa


Investigation of the seabed is an important issue nowadays. For this purpose, ultrasound images of the seabed provided from a side-scan sonar are often used for analysis. Two methods of analyzing the seabed are presented: automatic detection of objects on the seabed based on Haar-type feature and A daboost, and seabed sediments recognition using HLAC feature and the subspace method. Experimental results using real seabed ultrasound images are shown.
