OBA-Research/VAAS

VAAS is an inference-first, research-driven library for image integrity analysis. It integrates Vision Transformer Attention Mechanisms with patch-level self-consistency analysis to enable fine-grained localization and detection of visual inconsistencies across diverse image analysis tasks.

This tool helps researchers, digital forensics experts, and content evaluators analyze images to detect subtle visual inconsistencies that might indicate manipulation or anomalies. You input an image, and it outputs a set of numerical scores indicating global and local anomaly intensity, along with a visual heatmap highlighting suspicious areas. This helps you identify images that might have been altered or generated.

Available on PyPI.

Use this if you need to determine the integrity of an image and pinpoint specific regions that appear anomalous or potentially manipulated.

Not ideal if you need a simple 'yes/no' binary decision on image authenticity without detailed anomaly scoring or visual explanations.
