FU-Mamba: A Frequency-Enhanced Dynamic Scanning Framework for Oralscan Image Segmentation

FU-Mamba is a new framework for oralscan image segmentation that combines dynamic scanning with frequency domain enhancement. It introduces a Dynamic Mamba Block that learns adaptive sampling offsets for content‑aware scanning, preserving spatial coherence, and a frequency enhancement block that balances spectral components using wavelet‑guided decomposition and spectrum pooling. Experiments show a 1.1% improvement in mean intersection over union on a dental segmentation dataset.

FU-Mamba: A Frequency-Enhanced Dynamic Scanning Framework for Oralscan Image Segmentation

FU‑Mamba is a new framework for oralscan image segmentation that combines dynamic scanning with frequency‑domain enhancement. It uses a Dynamic Mamba Block to learn adaptive sampling offsets and perform bilinear interpolation, preserving spatial coherence, and a frequency enhancement block that balances spectral components via wavelet‑guided decomposition and spectrum pooling. Experiments show a 1.1% improvement in mean intersection over union on a dental segmentation dataset.

TLNM: Externally Validated Tooth Detection, Numbering and Segmentation from Smartphone Photographs Using Mask R-CNN

The paper presents TLNM, a Mask R‑CNN based system that detects, numbers, and segments teeth in smartphone photographs. It incorporates a masked gray‑world white‑balancing step and an anatomically constrained detection layer to handle patient‑generated variability. Evaluated on internal and external datasets, the model achieved high AP50, PQ, and F1 scores, demonstrating robust performance across diverse populations and imaging conditions.

FAN-LoRA: A Fourier-Adaptive Nonlinear Low-Rank Adaptor for Medical Foundation Model Domain Adaptation

The paper introduces FAN-LoRA, a Fourier‑adaptive nonlinear low‑rank adaptor designed to improve domain adaptation of vision foundation models like SAM for medical imaging. By decoupling frequency components into a low‑pass B‑spline branch for global structure and a high‑pass Fourier branch for local texture, FAN‑LoRA addresses performance drops caused by domain shifts. Experiments on three cross‑modality and cross‑center benchmarks show that FAN‑LoRA outperforms existing PEFT methods, achieving higher Dice scores and lower boundary errors while remaining computationally efficient.
