Latest 50 papers on image segmentation: Oct. 6, 2025

Image segmentation, the art of partitioning an image into multiple segments or objects, remains a cornerstone of computer vision and a critical enabler for countless AI applications. From pinpointing brain tumors to guiding autonomous robots and even defining virtual fashion, its accuracy and efficiency are paramount. However, the field grapples with challenges like data scarcity, computational overhead, and the need for greater interpretability. Recent research, as highlighted by a collection of innovative papers, is pushing the boundaries, offering novel solutions that promise more precise, robust, and accessible segmentation models.

The Big Idea(s) & Core Innovations

At the heart of these advancements is a multifaceted approach, blending architectural innovations, efficient training strategies, and novel ways to integrate contextual knowledge. A key theme emerging is the harmonization of global and local features, often through hybrid architectures. For instance, SwinMamba, from Zhiyuan Wang, Yanmin Liu, Xiaoxiao Zhang, and Jiawei Chen, introduces a hybrid model combining Mamba and convolutional architectures to enhance remote sensing semantic segmentation by capturing both local and global contextual information effectively. Similarly, Weitong Wu et al.’s HybridMamba (https://arxiv.org/pdf/2509.14609) takes this to 3D medical imaging, integrating spatial and frequency domain modeling with S-LMamba blocks and an FFT Gated Mechanism for robust feature fusion.

Another significant thrust is improving efficiency and adaptability, particularly for resource-constrained environments or specialized applications. G. He and W. Cheng’s tCURLoRA (https://arxiv.org/pdf/2501.02227) and Guanghua He et al.’s LoRA-PT (https://arxiv.org/pdf/2407.11292), both focused on medical image segmentation, introduce parameter-efficient fine-tuning (PEFT) methods leveraging tensor decomposition to drastically reduce trainable parameters while boosting transfer learning efficiency on limited data. This focus on efficiency extends to specialized applications like Canon Medical Systems Corporation’s Hidenori Takeshima and Shuki Maruyama’s work (https://arxiv.org/pdf/2510.00505) on a fast method for searching rectangular brain tumor regions, utilizing summed-area tables for up to 500x speedup.

Domain adaptation and generalization are also critical. Francesco Galati et al. from EURECOM and University College London introduce a semi-supervised Multi-Domain Brain Vessel Segmentation Through Feature Disentanglement (https://arxiv.org/pdf/2510.00665) framework, enabling accurate cross-modal vessel segmentation without extensive data harmonization. This is echoed in You Zhou et al.’s FedDA (https://arxiv.org/pdf/2509.23907) from Beihang University, which uses adversarial learning in a federated setting to align features across clients with different modalities, tackling the non-IID data challenge. For remote sensing, CVHub’s SAM2-ELNet (https://arxiv.org/pdf/2503.12404) enhances label quality and automates annotation, vastly improving efficiency for large-scale datasets.

Finally, the quest for interpretable AI and robust uncertainty quantification is gaining momentum. Matt Y. Cheung et al. from Rice University present COMPASS (https://arxiv.org/pdf/2509.22240), a framework for metric-based conformal prediction in medical segmentation, offering tighter prediction intervals and robust coverage under covariate shifts. P. Knab et al., supported by German ministries, introduce DSEG-LIME (https://arxiv.org/pdf/2403.07733), which integrates foundation segmentation models like SAM into LIME to provide semantically coherent and hierarchically structured explanations, moving “Beyond Pixels” to human-intuitive interpretability.
