Abstract

In this paper, we propose a novel segmentation approach that adapts the memory module of the Segment Anything Model 2 (SAM2) [15] for a category-sensitive segmentation within images. By combining SAM2’s Automatic Mask Generator (AMG) with a cross-modal attention mechanism, we build a dynamic memory bank that enables robust semantic associations of objects across frames. To mitigate challenges such as over-segmentation and reflection artifacts, we introduce an innovative fine-tuning strategy between the image encoder and mask decoder. This strategy substantially improves segmentation robustness while maintaining the model’s zero-shot generalization capability. Comparative experiments on ARMBench and real-world datasets demonstrate that our model performs effectively in both zero-shot and fine-tuned settings, adapting seamlessly to diverse environments. Ultimately, our approach empowers robotic systems with enhanced perceptual capabilities to recognize objects from selected categories within images.
