Image-Based Damage Assessment for Underwater Inspections

Inspection is crucial to the management of ageing infrastructure. Visual information on structures is regularly collected but very little work exists on its organised and quantitative analysis, even though image processing can significantly enhance these inspection processes and transfer real financial and safety benefits to the managers, owners and users. Additionally, new opportunities exist in the fast evolving sectors of wind and wave energy to add value to image-basedinspection techniques.\nThis book is a first for structural engineers and inspectors who wish to harness the full potential of cameras as an inspection tool. It is particularly directed to the inspection of offshore and marine structures and the application of image-based methods in underwater inspections. It outlines a set of best practice guidelines for obtaining imagery, then the fundamentals of image processing are covered along with several image processing techniques which can be used to assess multiple damage forms: crack detection, corrosion detection, and depth analysis of marine growth on offshore structures. The book provides benchmark performance measures for these techniques under various visibility conditions using an image repository which will help inspectors to envisage the effectiveness of the techniques when applied. MATLAB® scripts and access to the underwater image repository are included so readers can run these techniques themselves.\nPractising engineers and managers of infrastructure assets are guided in image processing based inspection. Researchers can use this book as a primer, and it also suits advanced graduate courses in infrastructure management or on applied image processing.

The essential detective in your pocket—something to reach for when your writing needs that short, sharp shock of modern-day investigating Every writer has paused at some key point in the development of their story to wonder what happens in real life. How would the murder in my story be investigated by the police? How far can I go without leaving holes in the plot? Can I use low count DNA to identify the killer? How does a cop react to a bloated body or, even worse, just part of one? Written with answers to these questions in mind, this is the essential guide to police procedures and practice written specifically for writers. A handy reference book to dip into, or a textbook to guide you from the outset while you are still developing your plot, this guide will leave you confident that you have covered all angles of your thriller.
