Error resilient content-based image authentication over wireless channel
—The pervasive distribution of digital images triggers an emergent need of authenticating degraded images by lossy compression and transmission. This paper proposes a robust cont...

3D Objects Coding and Recognition Using Surface Signatures
This paper presents a new concept for 3D coding of freeform surfaces. The proposed coding technique uses the surface signature representation scheme [1]. This representation schem...

Efficient Algorithms for String-Based Negative Selection
Abstract. String-based negative selection is an immune-inspired classification scheme: Given a self-set S of strings, generate a set D of detectors that do not match any element of...

Very fast watermarking by reversible contrast mapping
—Reversible contrast mapping (RCM) is a simple integer transform that applies to pairs of pixels. For some pairs of pixels, RCM is invertible, even if the least significant bits...

Truly selective polygonal mesh hierarchies with error control
In this work a new multi-resolution model is proposed for polygonal meshes. It is based on the dual edge collapse, which performs face clustering instead of vertex clustering. The...
