Sonar, Seismic and Ultrasound Computation Methods Related work: see presentation by Ido
Yariv and Talmor at my Advanced Seminar. A recent project was started on the infrasound
properties of the mole rat and the way it acquires information about the
underground environment from infrasound. Mathematical
Properties of the Cross-correlation Function This is a topic requires some knowledge in large deviation bounds,
such as the Barankin bound, and the Ziv Lemple bound. Some overview of the
topic appears in Judah’s thesis. The goal is to
analyze the properties of the cross correlation function from multiple sonar
returns with the purpose of devising an optimal fusion of the information that
can be extracted from each of the cross-correlations. A simple paper on this
topic is Robust statistics from multiple pings improves
noise tolerance in sonar. Ultrasound
Image Enhancement using Multiple Pings This work relies on the work that we did with enhancement of Sonar
images using multiple pings and attempts to apply the same concept for
medical ultrasound. It relies on the multiple pings idea (Robust statistics from multiple pings improves
noise tolerance in sonar) and robust motion estimation of
the ultrasound sensor (Multiple ping sonar accuracy improvement using
robust motion estimation and ping fusion). The goal is to
achieve a far more accurate ultrasound with less energy for lower damage to
the fetus. Neuronal
Optimal Coding Related work: Neuronal Goals: Efficient Coding and Coincidence
Detection. High
Dimensional Data Representation via Sound Related work: J. Berger and R. Coifman. This project
is done in collaboration with Miri Segal (PhD in Math and Visual & Audio
Artist) and Assaf Talmudi (PhD in Acoustics, and Musician) from the center
for Digital Art in The idea is to provide acoustic information as an
additional aid to visual information and thus extending the number of free
dimensions which can be ‘observed’ concurrently. This is important when a lot
of information has to be analyzed together, for example a radiologist that
has to decide about a malignant tumor, can get additional about a wider
spectrum of the target via sound. |
