Graph-based representation for multiview image coding
Thomas Maugey, Antonio Ortega, Pascal Frossard
In this paper, we propose a new representation for multiview image sets. Our approach relies on graphs to describe geometry information in a compact and controllable way. The links…
Localized Iterative Methods for Interpolation in Graph Structured Data
Sunil K. Narang, Akshay Gadde, Eduard Sanou +1
In this paper, we present two localized graph filtering based methods for interpolating graph signals defined on the vertices of arbitrary graphs from only a partial set of samples…
Bilateral Filter: Graph Spectral Interpretation and Extensions
Akshay Gadde, Sunil K Narang, Antonio Ortega
In this paper we study the bilateral filter proposed by Tomasi and Manduchi, as a spectral domain transform defined on a weighted graph. The nodes of this graph represent the pixel…
Object-based high contrast travel time tomography
Yenting Lin, Antonio Ortega
We consider travel time tomography problems involving detection of high contrast, discrete high velocity structures. This results in a discrete nonlinear inverse problem, for which…
P3: Toward Privacy-Preserving Photo Sharing
Moo-Ryong Ra, Ramesh Govindan, Antonio Ortega
With increasing use of mobile devices, photo sharing services are experiencing greater popularity. Aside from providing storage, photo sharing services enable bandwidth-efficient d…
