An Image Secret Sharing Scheme with the Capability of Previvewing the Secret Image
Some (k, n)-threshold image secret sharing schemes encrypt the secret image into n noise-like shadow images with size 1/k times that of the original secret image. The small size o...

Exact Evaluation of Non-Polynomial Subdivision Schemes at Rational Parameter Values
In this paper, we describe a method for exact evaluation of a limit mesh defined via subdivision on a uniform grid of any size. Other exact evaluation technique either restrict t...
