ForgeryVCR

ForgeryVCR is a visual-centric image-forensics agent built on Qwen3-VL-4B-Instruct. It actively calls ELA, FFT, NPP, and Zoom-In tools, classifies an image as authentic or tampered, and localizes manipulated regions with bounding boxes.

The released merged GRPO checkpoint is stored under GRPO/.
