ALT A copy of my SMM22 poster, entitled Automatic Photo-Identification of Cetaceans Using Deep Learning. OVERVIEW: Multi stage pipeline of trained neural networks Automatically detect fins via a Mask R-CNN network using pixel overlap Detected fins are cleaned then sent for catalogue matching via a Siamese Neural Network (SNN) SNN creates a numeric representation of the fin (Fin Embeddings) Comparison of representation allows for catalogue matching Can be used to flag possible previously unseen individuals RESULTS: System components tested on catalogues covering a range of locations, times, and species to ensure generalisability. Detector (Mask-RCNN): Tursiops aduncus, Tanzania: 91% pixel overlap. Total # fins = 616 T. truncatus & Lagenorhynchus albirostris, UK: 96% pixel overlap. # fins = 2900 Catalogue Matcher (SNN): T. truncatus & L. albirostris, UK: 83% ID within 10 MLM. # of classes = 44 T. truncatus, USA: 97% ID within 10 MLM. # of classes = 23
