Marine mammals use sound to navigate and to detect predators and prey. They use echolocation to obtain environmental information such as water depth , the location of food or the distance of objects. This means that marine mammals make use of sound almost continually. The types of sounds they use are versatile like the ammount of existing species.
During this thesis existing pitch estimation methods should be implemented and compared in unse on underwater biosignals. Therefore a literature serarch should give the upt to date estimation methods. These should be implemented under Matlab and compared to each other under the focus of robustness and calculation costs. Therefore a database with sounds of different species in different ambient noise scenarios is available. The estimation scheme with the best common performance and robustness should be implemented as a plugin for the DSS real-time framework using C.
