An Algorithm of Camera Sabotage Detection Using Contourlet
Authors: , , ,
Abstract: Contourlet is one of the new topics in image processing and video processing. Besides a lot of theoretical works about contourlet transform, its applications have roused enough interest as a critical means of multi-scale geometric analysis. This article, focusing on camera sabotage detection, extends the application of contourlet trans- form to video processing. A new algorithm to detect camera sabotage based on contourlet transform is proposed and experiment results show that the proposed algorithm is powerful and more efficient. Moreover, a comparison of results obtained by this algorithm and the one based on the 9-7 wavelet is made.
