Based on digital image forensics edge characteristic morphological filtering technology

摘要

For the number of buildings in the most commonly forged composite image blur operation, this paper presents an image forensics morphological filtering algorithm based on edge characteristics; The method uses homomorphic filtering and morphological filtering method to enhance the operation of the fuzzy image edge analyzed defocus blur and artificial blurred boundary characteristics, the use of artificial edge blur and defocus blur characteristics achieved for passive blind digital image forgery evidence; experiments show that this method can effectively detect forged digital images fuzzy operation marks and the partial image has been able to accurately locate the fuzzy operation.
