An access control video watermarking method that is robust to geometric distortions
: A new video watermarking algorithm for access control is introduced. This method is content-dependent and uses the dual tree complex wavelet transform (DT CWT) to create a waterm...

Improved watermark detection robust to camcorder capture based on quadrangle estimation
In this paper, we propose a blind watermark detection scheme which is robust against composite geometric distortions. The composite geometric distortions mean that an image or a v...
