COCO-CMFD A synthetic copy-move forgery dataset generated from MS-COCO 2017, with source/target-separated ground truth for copy-move forgery detection (CMFD). Each sample takes one annotated COCO object, applies a mild affine transform, and pastes it elsewhere in the same image at a location that passes scene-plausibility checks (support surface, horizon band, perspective scale, occlusion). Ground truth is provided as a 3-class trimap, a binary mask, a 16 px patch-label grid… See the full description on the dataset page: https://huggingface.co/datasets/harshitajainn/coco-cmfd.
