SAM-DCE: Decoupled Context Enhancement for Prompt-Free Medical Image Segmentation

Read the original on arXiv Computer Vision →

SAM-DCE is a framework that adapts the Segment Anything Model (SAM) for fully automatic, prompt‑free medical image segmentation. It introduces Spatial Representation Compensation (SRC) to recover fine anatomical details from intermediate Vision Transformer features and Semantic Token Calibration (STC) to enhance the consistency of foreground mask tokens. By refining spatial and semantic representations before using SAM’s original token‑to‑mask mechanism, SAM‑DCE achieves superior performance on the Synapse multi‑organ CT segmentation dataset, with a mean Dice score of 83.86% and an HD95 of 16.04 mm, outperforming several CNN, Transformer, and SAM baselines.

SEG-SAM: Semantic-Guided SAM for Unified Medical Image Segmentation

SEG-SAM is a unified medical image segmentation model that builds on the Segment Anything Model (SAM) by integrating semantic medical knowledge. It introduces a semantic‑aware decoder separate from SAM’s original decoder to handle both semantic segmentation of prompted objects and classification of unprompted objects. The model also incorporates key medical category characteristics from large language models via a text‑to‑vision semantic module and uses a cross‑mask spatial alignment strategy to improve overlap between predictions, achieving superior performance over existing SAM‑based and task‑specific methods.

Feature Reconfiguration With Visual Prior for Medical Lesion Segmentation

The paper introduces FreNet, a feature reconfiguration framework that incorporates visual priors for medical lesion segmentation. FreNet performs pixel‑level reconfiguration before encoding using an Implicit Prior Neural Network (IPNN) that leverages SAM, and feature‑level reconfiguration during encoding via a Dual‑domain Feature Reconfiguration (DFR) module, which includes a Frequency Decoupling Module (FDM) and a Spatial Localization Module (SLM). Experiments on nine benchmarks across three imaging modalities show that FreNet outperforms state‑of‑the‑art methods, achieving a 5.0% Dice improvement over the best baseline on the ETIS dataset and a 7.2% improvement over SAM.
