CF Model: A Coarse-to-Fine Model Based on Two-Level Local Search for Image Copy-Move Forgery Detection

<div>Copy-move forgery detection results for the JPEG. Top to bottom: test images from dataset, ground-truth forged regions, and forged regions detected by the proposed algorithm. Left to right, the quality factor is 20, 30, 40, 50, 60, 70, 80, and 90.</div>
