Interactive Medical Image Analysis with Concept-based Similarity Reasoning

CVPR 2025poster

The ability to interpret and intervene model decisions is important for the adoption of computer-aided diagnosis methods in clinical workflows. Recent concept-based methods link the model predictions with interpretable concepts and modify their activation scores to interact with the model. However,…

Looking in the Mirror: A Faithful Counterfactual Explanation Method for Interpreting Deep Image Classification Models

ICCV 2025poster

Counterfactual explanations (CFE) for deep image classifiers aim to reveal how minimal input changes lead to different model decisions, providing critical insights for model interpretation and improvement. However, existing CFE methods often rely on additional image encoders and generative models to…

Seeing the Trees for the Forest: Rethinking Weakly-Supervised Medical Visual Grounding

ICCV 2025poster

Visual grounding (VG) is the capability to identify the specific regions in an image associated with a particular text description. In medical imaging, VG enhances interpretability by highlighting relevant pathological features corresponding to textual descriptions, improving model transparency and…

CAPE: CAM as a Probabilistic Ensemble for Enhanced DNN Interpretation

CVPR 2024poster

Deep Neural Networks (DNNs) are widely used for visual classification tasks but their complex computation process and black-box nature hinder decision transparency and interpretability. Class activation maps (CAMs) and recent variants provide ways to visually explain the DNN decision-making process…

Decomposing Disease Descriptions for Enhanced Pathology Detection: A Multi-Aspect Vision-Language Pre-training Framework

CVPR 2024poster

Medical vision language pre-training (VLP) has emerged as a frontier of research enabling zero-shot pathological recognition by comparing the query image with the textual descriptions for each disease. Due to the complex semantics of biomedical texts current methods struggle to align medical images…

Weakly-Supervised Video Anomaly Detection With Robust Temporal Feature Magnitude Learning

ICCV 2021poster

Anomaly detection with weakly supervised video-level labels is typically formulated as a multiple instance learning (MIL) problem, in which we aim to identify snippets containing abnormal events, with each video represented as a bag of video snippets. Although current methods show effective detectio…
