Y. Tan, J. K. Tan, H. Kim and S. Ishikawa, “On Analyzing the Structure of the Seabed,” Proceedings of the Annual Conference of Biomedical Fuzzy System Association in Sapporo, 2013.
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 Adaboost, and seabed sediments recognition using HLAC feature and the subspace method. Experimental results using real seabed ultrasound images are shown.
