MaskDiME: Adaptive Masked Diffusion for Precise and Efficient Visual Counterfactual Explanations

CVPR 2026

Visual counterfactual explanations aim to reveal the minimal semantic modifications that can alter a model's prediction, providing causal and interpretable insights into deep neural networks. However, existing diffusion-based counterfactual generation methods are often computationally expensive, slo

Channel Attention Residual U-Net for Retinal Vessel Segmentation

ICASSP 2021accepted

Retinal vessel segmentation is a vital step for the diagnosis of many early eye-related diseases. In this work, we propose a new deep learning model, namely Channel Attention Residual U-Net (CAR-UNet), to accurately segment retinal vascular and non-vascular pixels. In this model, we introduced a nov…

Dense Residual Network for Retinal Vessel Segmentation

ICASSP 2020accepted

Retinal vessel segmentation plays an imaportant role in the field of retinal image analysis because changes in retinal vascular structure can aid in the diagnosis of diseases such as hypertension and diabetes. In recent research, numerous successful segmentation methods for fundus images have been p…
