Spatial averaging based steganalysis scheme to detect antipodal watermarks
Salil Kashyap, Prabin Kumar Bora · 2010
This paper proposes a new frame-by-frame averaging based steganalysis method. The test frame is passed through two low-pass filters simultaneously and the difference of the filter outputs is tested for Gaussianity. Experimental results on antipodal watermarked videos show performance comparable to that of the Wiener filter based steganalysis.
