Threading Software Watermarks
We introduce a new dynamic technique for embedding robust software watermarks into a software program using thread contention. We show the technique to be resilient to many semanti...

RST-Invariant Semi-fragile Image Authentication Based on DWT-Coefficient Quantization
Abstract. In this paper, we propose an image moment-based geometric normalization to be applied before embedding and extracting a digital watermark in the DWT-domain of JPEG2000. A...

Spread spectrum-based watermarking for Tardos code-based fingerprinting for H.264/AVC video
In this paper, we present a novel approach for active fingerprinting of state of the art video codec H.264/AVC. Tardos probabilistic fingerprinting code is embedded in H.264/AVC v...

3D Reconstruction of Human Faces from Occluding Contours
Abstract. In this paper we take a fresh look at the problem of extracting shape from contours of human faces. We focus on two key questions: how can we robustly fit a 3D face mode...
