AVA-Bench: Atomic Visual Ability Benchmark for Vision Foundation Models

Zheda Mai, Arpita Chowdhury, Zihe Wang +5

The rise of vision foundation models (VFMs) calls for systematic evaluation. A common approach pairs VFMs with large language models (LLMs) as general-purpose heads, followed by ev…

Static Segmentation by Tracking: A Label-Efficient Approach for Fine-Grained Specimen Image Segmentation

Zhenyang Feng, Zihe Wang, Jianyang Gu +22

We study image segmentation in the biological domain, particularly trait segmentation from specimen images (e.g., butterfly wing stripes, beetle elytra). This fine-grained task is…

Prompt-CAM: Making Vision Transformers Interpretable for Fine-Grained Analysis

Arpita Chowdhury, Dipanjyoti Paul, Zheda Mai +10

We present a simple approach to make pre-trained Vision Transformers (ViTs) interpretable for fine-grained analysis, aiming to identify and localize the traits that distinguish vis…

Finer-CAM: Spotting the Difference Reveals Finer Details for Visual Explanation

Ziheng Zhang, Jianyang Gu, Arpita Chowdhury +5

Class activation map (CAM) has been widely used to highlight image regions that contribute to class predictions. Despite its simplicity and computational efficiency, CAM often stru…
