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...

On the relation between Memon's and the modified Zeng's palette reordering methods
Palette reordering has been shown to be a very effective approach for improving the compression of color-indexed images by general purpose continuous-tone image coding techniques....

Digital Single Lens Reflex Camera Identification From Traces of Sensor Dust
Abstract--Digital single lens reflex cameras suffer from a wellknown sensor dust problem due to interchangeable lenses that they deploy. The dust particles that settle in front of ...
