The extreme operational environmental conditions and aging of subsea structures pose a risk to their structural integrity is critical safety. Nondestructive testing essential identify defects developing within the structure, allowing repair in timely manner mitigate against failures that cause damage environment hazard human operators. However, be cost effective, inspections must carried out wi...

Quantitative measurements of macroscopic neural anatomy that are obtained from MRI scans are beginning to be used in clinical trials. This paper describes procedures and software features that ensure the demonstrable validity of these measurements. In addition to describing mechanisms that provide data integrity and security throughout the image analysis pipeline, we present “SegMentor”, a syst...

This study examines conductive noise in long distance cables in a subsea environment. The conductive noise was caused by impedance mismatch between cables and appeared in the form of transient voltages. In particular, it is important to analyze the characteristics of transient voltages for different subsea temperature changes. To analyze the transient voltages, the effects of L, R, and C for di...

| This paper proposes a robust feature tracker based on an eecient outlier rejection scheme, suitable for feature tracking in subsea video sequences. We extend the Shi-Tomasi-Kanade scheme by introducing a technique for rejecting spurious features. We employ a simple and ee-cient outlier rejection rule, called X84, and prove that its theoretical assumptions are satissed in the feature tracking ...

The changes of the seabed environment caused by a natural disaster or human activities dramatically affect the life span of the subsea buried cable. It is essential to track the cable route in order to inspect the condition of the buried cable and protect its surviving seabed environment. The magnetic sensor is instrumental in guiding the remotely-operated vehicle (ROV) to track and inspect the...

Offshore subsea pipelines are used to export oil and gas from the field to platform and then from the platform to the mainland. As they are the sole conduit for the hydrocarbons their stability and integrity are of critical economic and environmental importance. With more than 80 per cent of Australia’s gas resources in deep, remote, offshore areas, the ability to realise their full potential r...
