WebMar 26, 2024 · Abstract. Copy-move image forgery detection (CMIFD) via SIFT algorithm is one of the emerging and effective key-point based strategies. This algorithm is robust against large-scale geometric transformations and various attacks during the forgery process. CMIFD via SIFT algorithm accurately localizes the tampered regions rich in … Webcreate. public static SIFT create (int nfeatures, int nOctaveLayers) Parameters: nfeatures - The number of best features to retain. The features are ranked by their scores (measured in SIFT algorithm as the local contrast) nOctaveLayers - The number of layers in each octave. 3 is the value used in D. Lowe paper.
