Estimating the Optimal Quantization Parameter in H.264
The quantization parameter (QP) has a very important impact on the compression rate in H.264. In this paper we show that in order to achieve efficient rate-control coding a good e...

Rotation, scaling, and translation-invariant multi-bit watermarking based on log-polar mapping and discrete Fourier transform
This paper proposes an RST-invariant multi-bit watermarking system based on LPM and DFT. This system embeds the watermark in a rotation and translation invariant domain obtained b...

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...

Modern steganalysis can detect YASS
YASS is a steganographic algorithm for digital images that hides messages robustly in a key-dependent transform domain so that the stego image can be subsequently compressed and d...
