As an important pillar of underwater intelligence, Marine Animal Segmentation (MAS) involves segmenting animals within marine environments. Previous methods don't excel in extracting long-range contextual features and overlook the connectivity between pixels. Recently, Segment Anything Model (SAM) offers a universal framework for general segmentation tasks. Unfortunately, trained with natural images, SAM does not obtain the prior knowledge from marine images. In addition, the single-position prompt of SAM is very insufficient for prior guidance. To address these issues, we propose a novel learning framework, named Dual-SAM for high-performance MAS. To this end, we first introduce a dual structure with SAM's paradigm to enhance feature learning of marine images. Then, we propose a Multi-level Coupled Prompt (MCP) strategy to instruct comprehensive underwater prior information, and enhance the multi-level features of SAM's encoder with adapters. Subsequently, we design a Dilated Fusion Attention Module (DFAM) to progressively integrate multi-level features from SAM's encoder. With dual decoders, it generates pseudo-labels and achieves mutual supervision for harmonious feature representations. Finally, instead of directly predicting the masks of marine animals, we propose a Criss-Cross Connectivity Prediction ( C3P) paradigm to capture the inter-connectivity between pixels. It shows significant improvements over previous techniques. Extensive experiments show that our proposed method achieve state-of-the-art performances on five widely-used MAS datasets.
- [Dual-SAM] is a novel learning framework for high performance Marine Animal Segmentation (MAS). The framework inherits the ability of SAM and adaptively incorporate prior knowledge of underwater scenarios.

We rely on five public datasets and five evaluation metrics to thoroughly validate our model’s performance.
step1:Clone the Dual_SAM repository:
To get started, first clone the Dual_SAM repository and navigate to the project directory:
git clone https://github.com/Drchip61/Dual_SAM.git
