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...

One Sided Error Predicates in Geometric Computing
A conservative implementation of a predicate returns true only if the exact predicate is true. That is, we accept a one sided error for the implementation. For geometric predicate...
