Latest 50 papers on segment anything model: Sep. 29, 2025

The Segment Anything Model (SAM) has rapidly become a cornerstone in computer vision, offering remarkable zero-shot segmentation capabilities across diverse image types. Yet, the real magic unfolds as researchers and engineers push its boundaries, adapting and augmenting SAM to conquer complex, real-world challenges. From enhancing medical diagnostics to automating industrial tasks and deciphering remote sensing data, recent breakthroughs are transforming SAM from a powerful concept into an indispensable tool. This post dives into these exciting advancements, highlighting how the community is refining SAM’s precision, efficiency, and semantic understanding.### The Big Idea(s) & Core Innovationsresearch largely centers on two core themes: enhancing SAM’s semantic understanding and boosting its efficiency and adaptability for specialized tasks. Many papers explore how to imbue SAM with domain-specific intelligence, moving beyond its class-agnostic nature.instance, the groundbreaking work on Repurposing SAM for User-Defined Semantics Aware Segmentation by Rohit Kundu and Amit K. Roy-Chowdhury from the University of California, Riverside, introduces U-SAM. This framework enables SAM to generate masks for user-defined object categories without manual supervision, leveraging synthetic or web-crawled images. Similarly, LENS: Learning to Segment Anything with Unified Reinforced Reasoning by Lianghui Zhu et al. from Huazhong University of Science & Technology, introduces a reinforcement learning framework that jointly optimizes reasoning and segmentation, improving generalization by incorporating chain-of-thought reasoning and multi-modal alignment.the medical domain, adaptability and precision are paramount. Muhammad Alberba et al. from the University of Toronto, in Live(r) Die: Predicting Survival in Colorectal Liver Metastasis, developed SAMONAI, a zero-shot 3D prompt propagation algorithm for efficient organ segmentation, crucial for survival analysis. Furthering medical precision, A Probabilistic Segment Anything Model for Ambiguity-Aware Medical Image Segmentation by Tyler Ward and Abdullah Imran from the University of Kentucky, introduces Probabilistic SAM, which captures inherent segmentation ambiguity in medical imaging by generating diverse, uncertainty-aware masks. This is vital for clinical decisions where uncertainty quantification is key.
