Finding GEMS: Multi-Scale Dictionaries for High-Dimensional Graph Signals
Yael Yankelevsky, Michael Elad
Modern data introduces new challenges to classic signal processing approaches, leading to a growing interest in the field of graph signal processing. A powerful and well establishe…
Structure-Aware Classification using Supervised Dictionary Learning
Yael Yankelevsky, Michael Elad
In this paper, we propose a supervised dictionary learning algorithm that aims to preserve the local geometry in both dimensions of the data. A graph-based regularization explicitl…
Component Based Modeling of Ultrasound Signals
Yael Yankelevsky, Zvi Friedman, Arie Feuer
This work proposes a component based model for the raw ultrasound signals acquired by the transducer elements. Based on this approach, before undergoing the standard digital proces…
Depth Perception in Autostereograms: 1/f-Noise is Best
Yael Yankelevsky, Ishai Shvartz, Tamar Avraham +1
An autostereogram is a single image that encodes depth information that pops out when looking at it. The trick is achieved by replicating a vertical strip that sets a basic two-dim…
On Optimal Disc Covers and a New Characterization of the Steiner Center
Yael Yankelevsky, Alfred M. Bruckstein
Given N points in the plane and a location , the union of discs with diameters covers the convex hull of the points. The location m…
