Efficient down-up sampling using DCT kernel for MPEG-21 SVC
Down-up sampling of images is an essential process for spatial scalability of the video coding standard. We propose an efficient down-up sampling method in spatial domain using DC...

Towards unifying diffusion and exemplar-based inpainting
A novel framework for image inpainting is proposed, relying on graph-based diffusion processes. Depending on the construction of the graph, both flow-based and exemplar-based inpa...

Subspace Extension to Phase Correlation Approach for Fast Image Registration
A novel extension of phase correlation to subspace correlation is proposed, in which 2-D translation is decomposed into two 1-D motions thus only 1-D Fourier transform is used to ...

Optimal strategies for spread-spectrum and quantized-projection image data hiding games with BER payoffs
We analyze spread-spectrum and quantization projection data hiding methods from a game-theoretic point of view, using the bit error rate (BER) as the payoff, and assuming that the...

Imaging of fast moving targets using undersampled SAR raw-data
The paper proposes a novel methodology to estimate the velocity of fast moving targets using a single synthetic aperture radar sensor without increasing the Pulse Repetition Frequ...
