Sea Ice Image Processing with MATLAB addresses the topic of image processing for the extraction of key sea ice characteristics from digital photography, which is of great relevance for Artic remote sensing and marine operations. This valuable guide provides tools for quantifying the ice environment that needs to be identified and reproduced for such testing. This includes fit-for-purpose studies of existing vessels, new-build conceptual design and detailed engineering design studies for new developments, and studies of demanding marine operations involving multiple vessels and operational scenarios in sea ice. A major contribution of this work is the development of automated computer algorithms for efficient image analysis. These are used to process individual sea-ice images and video streams of images to extract parameters such as ice floe size distribution, and ice types. Readers are supplied with Matlab source codes of the algorithms for the image processing methods discussed in the book made available as online material.

Prof. Roger Skjetne received his MSc degree in 2000 in control engineering at the University of California at Santa Barbara, and his PhD degree in 2005 at the Norwegian University of Science and Technology (NTNU), for which his thesis was awarded the Exxon Mobil prize for best PhD thesis in applied research. Prior to his studies, he worked as an electrician for Aker Elektro AS on numerous oil installations for the North Sea. In 2004-2009 he was employed in Marine Cybernetics AS, working on Hardware-In-the-Loop (HIL) simulation for testing safety-critical marine control systems. From August 2009 he has held the position of Professor in Marine Control Engineering at the Department of Marine Technology at NTNU, where he presently is the leader of the research group on Marine Structures. His research interests are within Arctic stationkeeping operations and Ice Management systems for ships and rigs, environmentally robust control of shipboard electric power systems, and nonlinear control theory for motion control of single and groups of marine vessels. Roger Skjetne is leader of the ice management work package in the CRI Sustainable Arctic Marine and Coastal Technology (SAMCoT), associated researcher in the CoE Centre for Ships and Ocean Structures (CeSOS) and CoE Autonomous Marine Operations and Systems (AMOS), principal researcher in the CRI on Marine Operations (MOVE), and he was project manager for the KMB Arctic DP research project. He is also co-founder of the two companies BluEye Robotics and ArcISo.
