Latest 50 papers on segment anything model: Sep. 1, 2025

The AI/ML landscape is continuously evolving, and at its heart lies the formidable challenge of understanding and segmenting visual data with human-like precision. Enter the Segment Anything Model (SAM)—a groundbreaking foundation model that has revolutionized image segmentation. SAM’s remarkable ability to generalize to unseen objects and domains with zero-shot capabilities has ignited a flurry of innovation, pushing the boundaries of what’s possible in diverse fields, from medical imaging to robotics and remote sensing. This post delves into recent breakthroughs, synthesized from cutting-edge research, showcasing how SAM and its successors, like SAM2, are being adapted, enhanced, and deployed to tackle complex real-world problems.

The Big Idea(s) & Core Innovations

Many recent papers center on refining SAM’s core capabilities—zero-shot generalization and precise segmentation—while addressing domain-specific challenges. A significant theme is the adaptation of SAM for medical imaging. For instance, E-BayesSAM: Efficient Bayesian Adaptation of SAM with Self-Optimizing KAN-Based Interpretation for Uncertainty-Aware Ultrasonic Segmentation by Yi Zhang, Chao Li, Xiaowei Zhou from Shenzhen University introduces a Bayesian adaptation to make SAM uncertainty-aware and more efficient for ultrasonic segmentation. This involves reformulating SAM’s output tokens as dynamic Gaussian-distributed weights, accelerating variational Bayesian inference, and utilizing a Self-Optimizing KAN (SO-KAN) for interpretability and token pruning, crucial for safety-critical medical tasks.

Similarly, MAUP: Training-free Multi-center Adaptive Uncertainty-aware Prompting for Cross-domain Few-shot Medical Image Segmentation by Y. Zhu et al. (National Natural Science Foundation of China) presents a training-free framework that uses adaptive prompting to enhance cross-domain few-shot medical image segmentation. This bypasses the need for extensive training data, a perennial challenge in healthcare. Further in medical applications, Multi-Sequence Parotid Gland Lesion Segmentation via Expert Text-Guided Segment Anything Model (Zhongyuan Wu et al. from Sun Yat-Sen University) integrates expert diagnostic text with SAM to guide segmentation, removing the dependency on manual annotations. This text-guided approach is a prime example of injecting domain knowledge to improve accuracy, particularly in multi-sequence imaging.

Beyond medicine, CLUE: Leveraging Low-Rank Adaptation to Capture Latent Uncovered Evidence for Image Forgery Localization (Youqi Wang et al. from Shenzhen University) ingeniously repurposes Stable Diffusion 3 (SD3) and SAM for image forgery localization. By fine-tuning SD3 with Low-Rank Adaptation (LoRA), CLUE detects subtle statistical inconsistencies in forged images, shifting the focus from artifact-based detection to understanding generative principles. In remote sensing, MergeSAM: Unsupervised change detection of remote sensing images based on the Segment Anything Model (Meiqi Hu et al. from Sun Yat-sen University) introduces MaskMatching and MaskSplitting strategies for unsupervised change detection in high-resolution satellite imagery, leveraging SAM’s power without requiring training samples.

Under the Hood: Models, Datasets, & Benchmarks

These innovations are often enabled by novel models, datasets, or clever adaptations of existing ones:

• ZIM: Zero-Shot Image Matting for Anything (Beomyoung Kim et al. from NAVER Cloud) introduces SA1B-Matte, a new dataset with micro-level matte labels generated without manual annotation, along with MicroMat-3K for evaluation. This model preserves SAM’s zero-shot capability while achieving fine-grained mask precision.
• SPLF-SAM: Self-Prompting Segment Anything Model for Light Field Salient Object Detection (Qiyao Xu et al. from Sichuan University) proposes Multi-scale Adaptive Filtering Adapter (MAFA) and Unified Multi-scale Feature Embedding Block (UMFEB) to enhance small object detection in noisy light field environments, outperforming ten state-of-the-art methods.
• FreeVPS: Repurposing Training-Free SAM2 for Generalizable Video Polyp Segmentation (Qiang Hu et al. from Huazhong University of Science and Technology and Australian National University) introduces Intra-Association Filtering (IAF) and Inter-Association Refinement (IAR) modules to mitigate error accumulation in SAM2 for training-free video polyp segmentation, achieving state-of-the-art results on in-domain and out-of-domain datasets. Code is available for some implementations like SPGrasp and TSMS-SAM2.
• TSMS-SAM2: Multi-scale Temporal Sampling Augmentation and Memory-Splitting Pruning for Promptable Video Object Segmentation and Tracking in Surgical Scenarios (Guoping Xu et al. from University of Texas Southwestern Medical Center) utilizes multi-scale temporal sampling and memory-splitting pruning to improve robustness against rapid object motion and memory redundancy in surgical videos.
• Zero-shot Shape Classification of Nanoparticles in SEM Images using Vision Foundation Models (Freida Barnatan et al.) leverages SAM and DINOv2 for feature extraction and segmentation in scientific imaging, offering a scalable, low-computation solution for industrial applications.

Impact & The Road Ahead

The impact of these advancements is profound and far-reaching. From making medical diagnostics more accurate and less labor-intensive to enhancing robotic manipulation in dynamic environments (as seen in SPGrasp: Spatiotemporal Prompt-driven Grasp Synthesis in Dynamic Scenes by Sej Moon-Wei from UC Berkeley), SAM’s influence is undeniable. The ability to perform high-quality segmentation with minimal or no training data, often driven by intuitive prompts, democratizes access to advanced AI capabilities for domain experts. Frameworks like Zenesis (Shubhabrata Mukherjee et al. from Lawrence Berkeley National Laboratory) illustrate this by enabling zero-shot segmentation of scientific images without requiring AI-ready data, bridging the gap for non-AI specialists.

However, challenges remain. The review paper Segment Anything for Video: A Comprehensive Review of Video Object Segmentation and Tracking from Past to Future (Guoping Xu et al. from UT Southwestern Medical Center) highlights issues such as memory redundancy, error accumulation in long video sequences, and prompt inefficiency. Adversarial attacks also pose a threat, as demonstrated by SAM Encoder Breach by Adversarial Simplicial Complex Triggers Downstream Model Failures (Yi Qin et al. from Beijing Jiaotong University), emphasizing the need for robust foundation models.

The future of SAM-driven segmentation lies in hybrid models that combine the strengths of different approaches, improved robustness against real-world complexities, and more intuitive human-AI collaboration. The ongoing research into adapting and refining these models, from Rein++ for efficient generalization (Wenlong Liao et al. from Fudan University) to LENS for unified reinforced reasoning (Lianghui Zhu et al. from Huazhong University of Science & Technology and vivo AI Lab), promises an exciting era where AI vision systems are not just accurate but also adaptable, efficient, and truly intelligent in understanding our complex world.
