Includes bibliographical references. "Visual sampling can be used to collect biological and ecological data in the marine environment in a minimally intrusive and non-extractive way. Deposited imaging devices are versatile, easy-to-use systems that can be deployed in various environments and enable the acquisition of large quantities of images. Extracting data from visual samples collected during imaging analysis is a time-consuming and expertise-intensive process that requires standardized and interoperable procedures. This report aims to help develop and optimize standardized procedures for analyzing photo and video samples from deposited systems, including the use of quadrats, bait and stereoscopy. A set of analysis practices, methods and strategies are described, making it possible to i) maximize the quality, quantity and diversity of the data collected; ii) take into account the methodological, ecological and environmental factors that influence the performance of sampling devices and the accuracy of imaging data; and iii) generate reliable data with quantifiable errors. These procedures can be applied to most marine environments and photo or video samples from deposited systems. Implementation of these procedures will enhance the contribution of underwater imaging to ecosystem-based management of marine environments"--Abstract, page ix.
