Mixed-resolution distributed video codec without motion estimation at the encoder
Inspired by recent results showing that Wyner-Ziv coding using a combination of source and channel coding may be more efficient than pure channel coding, we have applied coset cod...

Video denoising using a spatiotemporal statistical model of wavelet coefficients
We propose a video denoising algorithm based on a spatiotemporal Gaussian scale mixture (ST-GSM) model in the wavelet transform domain. This model simultaneously captures local co...

Memory-Centric Motion Estimator
In the streaming video processing domain, the only way to meet strict performance and quality requirements and yet to provide the area- and power-wise optimal platform is to apply...

Video coding with MC-EZBC and redundant-wavelet multihypothesis
Motion compensation with redundant-wavelet multihypothesis, in which multiple predictions that are diverse in transform phase contribute to a single motion estimate, is deployed i...

DCT-based motion estimation
—We propose novel discrete cosine transform (DCT) pseudophase techniques to estimate shift/delay between two onedimensional (1-D) signals directly from their DCT coefficients by...
