Abstract

The invention discloses an image tampering detection method and device, and relates to the technical field of computers. One specific embodiment of the method comprises the following steps: obtaininga plurality of standard images with the same size according to the to-be-detected image; obtaining feature vectors of the plurality of standard images through feature extraction, clustering the extracted feature vectors to obtain one or more aggregation regions of the to-be-detected image, analyzing whether each aggregation region is a tampered region or not, and if the aggregation region is the tampered region, judging that the to-be-detected image is the tampered image. Therefore, the detection success rate and the detection accuracy are high, the defect that an existing detection algorithmis complex is overcome, the time complexity is low, and the user experience is good.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an image tampering detection method and device. Background technique [0002] With the rapid development of digital technology, it is becoming easier and easier to use image processing software to repair, retouch, enhance and even tamper with images. It has become increasingly difficult for people to distinguish whether an image is an original image or has been processed by digital technology. past images. In news photography, judicial evidence collection, and especially in the fields of insurance claims, if images are maliciously tampered with, it will directly affect the results of the case and cause serious negative effects. Existing image tampering detection schemes are manually extracting features, building models, analyzing features and classifying them. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following p...
