1. Photographic mark–recapture is a cost-effective, non-invasive way to study populations. However , to efficiently apply photographic mark–recapture to large populations, computer software is needed for image manipulation and pattern matching. 2. We created an open-source application for the storage, pattern extraction and pattern matching of digital(More)
