| Abstract: | With the popularity of video editing software,the network is now filled with a large amount of processed and tampered video data.How to ensure the authenticity and integrity of the various digital videos has become a research hotspot in the field of multimedia area.In this paper a typical digital video tampering model which is based on copy-paste object-deletion technique is analyzed deeply.A spatial and temporal matching algorithm using regional correlation is proposed for detecting the copy-paste area.It can not be affected by the lossy compression encoding system and accurately determine the tampered area of the test video sequences. |
