Book Description
This book consists of the proceedings of the International Conference on Detection and Classification of Underwater Targets which took place in Brest, France, in October 2012. This collection of academic papers represents the current state of the art of research and development in the areas of sensor technology, processing, modeling and automation for the purpose of detecting and classifying objects in the underwater environment, written by leading researchers in government, industry and academia. These articles should be of interest not only to those working on underwater target detection, but also to researchers in the related fields of remote sensing, robotic perception and medical imaging.

Book Description
The problem of detecting underwater targets from Electro-optical (EO) images is considered in this paper. A blockbased log-likelihood ratio test has been developed for detection and segmentation of underwater mine-like objects in the EO images captured with a CCD-based image sensor. The main focus of this research is to develop a robust detection algorithm that can be used to detect low contrast and partial underwater objects from the EO imagery with low false alarm rate. The detection method involves identifying frames of interest (FOI) containing the potential targets. Once the FOI have been identified, regions of interest (ROI) within the FOI are segmented from the background. Performance of the detection method is tested in terms of probability of detection, false alarm rate, and receiver operating characteristic (ROC) curves for FOI in the selected data runs. The algorithm shows promising results in target detection and generation of good silhouettes for subsequent classification.

Book Description
This book gives a start-to-finish overview of the whole Fish4Knowledge project, in 18 short chapters, each describing one aspect of the project. The Fish4Knowledge project explored the possibilities of big video data, in this case from undersea video. Recording and analyzing 90 thousand hours of video from ten camera locations, the project gives a 3 year view of fish abundance in several tropical coral reefs off the coast of Taiwan. The research system built a remote recording network, over 100 Tb of storage, supercomputer processing, video target detection and tracking, fish species recognition and analysis, a large SQL database to record the results and an efficient retrieval mechanism. Novel user interface mechanisms were developed to provide easy access for marine ecologists, who wanted to explore the dataset. The book is a useful resource for system builders, as it gives an overview of the many new methods that were created to build the Fish4Knowledge system in a manner that also allows readers to see how all the components fit together.

Book Description
This report discusses a Broadband Bionic Sonar System and a signal processing technique for detection and identification of underwater targets. Since the sonar and radar target echoes are the solutions to the same Helmholtz Equation in their respective media, an Ultra Wideband Radar System can also be developed for target detection and identification base on the same principles and signal processing techniques. In the bionic sonar system with the resonance detection technique for detection and identification of underwater targets, it appears to mimic a dolphin's and/or a bat's acoustic sensory systems. It is conceivable that an Ultra-Wideband Radar System of the same detection technique can also be developed.

Book Description
The goal of this project was to develop an automated detection and tracking algorithm for broadband targets using complex hydrophone data from a passive acoustic array. The algorithm is an integral part of a larger Coherent Automated Multi-Target Tracker (CAMTT) system under development by Metron, Inc. for Detection, Classification, and Localization (DCL) for passive Anti-Submarine Warfare (ASW). The algorithm integrates the Maximum a Posteriori Penalty Function (MAP-PF) tracking algorithm with the Likelihood Ratio Detection and Tracking (LRDT) methodology. The detection and tracking problem is treated as a joint detection and estimation problem and the combined system automatically (1) detects and drops targets, (2) jointly estimates bearing vs. time tracks for all targets, and (3) jointly estimates the received spectrum of these targets. The spectral estimates improve the detection and tracking capability and are used to aid the classification component of the CAMTT system.
