Abstract:

Ship target segmentation plays a crucial role in enhancing the automation level of marine monitoring systems.However,the existing target segmentation methods often suffers from the issues such as mis-segmentation,susceptibility to noise interference,and low processing efficiency,making them difficult to adapt flexibly and efficiently to real-world scenarios.To address these challenges in maritime ship target segmentation tasks,a segmentation algorithm based on an improved DeepLabV3+ network,termed MET-DeepLabV3+,is proposed.During the image preprocessing stage,the bilateral filtering,multi-scale Retinex algorithm,and linear transformation are employed to mitigate the effects of noise,weather and other adverse factors.In terms of model design,the lightweight MobileNetV2 is used as the backbone network to reduce model complexity,and the ECA-Net attention mechanism is introduced to enhance the model's ability to capture the multi-scale features.Additionally,a transfer learning approach is adopted,and the feature weights pre-trained on the SeaShips dataset are applied to model training to further optimize the segmentation performance.Experimental results demonstrate that the improved algorithm achieves an average interaction-over-union (IoU) of 91.62% and an average pixel accuracy (PA) of 92.87%,which are improved by 2.13% and 1.11%,respectively,compared with those of the baseline DeepLabV3+ model.Moreover,it outperforms the segmentation models such as HRNet,PSPNet,and UNet,which effectively meets the practical demands of ship target segmentation tasks and offers significant application value.
