Effective and efficient pixel-level detection for diverse video copy-move forgery types

作者：

Highlights：

• An innovatively improved SIFT structure that addresses the thorough feature extraction in all forgery cases.

• A fast keypoint-label matching (FKLM) that creates groups of keypoint-label so that every high-dimensional feature is assigned into one of these groups.

• A coarse-to-fine filtering relying on intrinsic attributes of exact keypoint-matches is designed to reduce false keypoint-matches effectively.

• The adaptive block filling relying on true keypoint-matches contributes to the accurate and efficient suspicious region filling.
