Stripe segmentation of oceanic internal waves in synthetic …

WebbOceanic internal waves play an important role in ocean activities. To obtain the light and dark stripes from synthetic aperture radar (SAR) images, a stripe segmentation algorithm for oceanic internal waves is proposed based on Mask R-CNN. WebbMany scholars can invert internal waves (IWS) parameters through IWS SAR images by empirical mode decomposition and other methods. The inversion of depth, velocity and other parameters of underwater moving objects through SAR IWS images has become the target of current research. In this paper, by comparing the errors of half-open angle and … bki fkm-f service manual
