DefectFill: Realistic Defect Generation with Inpainting Diffusion Model for Visual Inspection

Reference Defect MVTec Images Real World Images Figure 1 . Given a few reference image-mask pairs of a defect (e.g. "hole" of a hazelnut), DefectFill learns the defect and realistically fill it onto defect-free objects in desired shapes (e.g. star, square, etc.), generating new defect images that integrate naturally with the objects. These generated images are then used for visual inspection tasks.
