Abstract

A method for automated real-time acquisition of a marine mammal in a natural body of water in the surroundings of a vessel includes detecting a thermal signature of the marine mammal is detected by imaging thermographic scanning of a water surface with an infrared camera system so as to generate an image data stream of consecutive images. A modular processing of the image data stream is performed including performing an image pre-processing, detecting local changes in contrast in the images, classifying the detected local changes in contrast so as to detect a pattern of the thermal signature of the marine mammal, localizing the classified thermal signature of the marine mammal, verifying the classified, localized thermal signature of the marine mammal and documenting the classified, localized and verified thermal signature of the marine mammal.
