摘要
Determination of the presence of a marine mammal with the aid of a detection of the thermal signature (tsmm), and can be manually or in a simpler observers, carried out only part - automated prototypes. In this case, the rapid and reliable image processing in combination with a high level of user friendliness problematic. In the method according to the invention take place in the image pre-processing (fpp) an image correction and unweighted fully - image segmentation (segments) in the snippets, in the detection (det) the use of a limit value - algorithm on the basis of detected local contrast changes, in the classification (cla) the use of monitored learning with the aid of the support vector method (svm) with a hyperplane (he) for the division into two classes, in the localization (loc) an automatic calculation of the distance of the detected thermal signature (tsmm) and their temporal and positional change in the ship (rv), in the verification (comparison) the possibility of an instantaneous checking of the decision by an operator, and in the documentation (doc) an automatic provision of application-specific image data (irv) of detected thermal signatures of marine mammal (tsmm). For the data generation, an infrared camera system (irc) with a fully - or part circle detection and an active gyroscopic stabilization with respect to the horizon (hz) is used.
