Outline

Marine imagery presents significant challenges for image understanding due to the dynamic nature of marine objects and their surroundings, camera motion, and the complexity of underwater scenes. Existing image caption datasets, which focus on general or human-centric domains, often fail to generalize the complexity of the marine environment and gain insights into marine life. To address these limitations, this paper proposes a two-stage marine object-oriented image captioning pipeline. We introduce a comprehensive image understanding benchmark leveraging three elements—image, text, and segmentation masks—to facilitate visual justification and caption generation, thereby enhancing marine image understanding and analysis, as well as marine image generation. Furthermore, we emphasize the effectiveness of image segmentation in detecting significant object transitions in scene changes, significantly enriching the semantics of caption content. The dataset and code are publicly available at https://msc.hkustvgd.com .

Takeaways, Limitations

Takeaways:
A new benchmark dataset and two-stage captioning pipeline for understanding ocean imagery are presented.
Detecting Important Object Transitions and Enriching Caption Meaning Using Image Segmentation
Contributing to improving understanding and analysis of marine imagery and the creation of marine imagery.
Sharing research and ensuring reproducibility through open datasets and code.
Limitations:
Further review is needed regarding the size and diversity of the proposed benchmark dataset.
The generalization performance of the proposed pipeline and its applicability to other marine environments need to be evaluated.
Further research is needed to determine whether it fully reflects the complexity of the actual marine environment.
