Abstract— This paper experimentally investigates the feasibility of crypto-free communications in resource-constrained wireless sensor networks. We exploit the spatial signature ...
Segmentation of femurs in Anterior-Posterior x-ray images is very important for fracture detection, computer-aided surgery and surgical planning. Existing methods do not perform we...
This paper describes an experimental study about a robust contour feature (shape-context) for using in action recognition based on continuous hidden Markov models (HMM). We ran dif...
This paper presents an oblivious real-time video watermarking scheme in which extended m-sequences is selected as watermark pattern. The good balance property of extended m-sequen...
In this paper, an affine invariant watermarking scheme, robust to geometric attacks, is proposed and applied to face regions. Initially, face regions are unsupervisedly extracted ...
