This report describes a set of software programs that were developed by the Alaska Fisheries Science Center for analyzing stereo images. The main application is called SEBASTES, and is used to count, range, and measure fish using stereo-image algorithms. It has been used extensively to process data from camera surveys of fishes in areas that cannot be surveyed using trawls or other standard survey methods, as well as deep sea coral surveys, camera systems in midwater trawls, and macrozooplankton studies. Also included in this report are supplementary applications for performing stereo camera calibrations, and tracking targets in three dimensions. The report is meant as a resource for those using the software, as well as a technical reference for the methods used to extract quantitative data from stereo images.
