Here are few demonstrations of our ONCET system, first on international challenge
on whale tracking using passive acoustics. The demonstrations data are public, from the
Detection and Localization of Marine Mammals Using Passive Acoustics workshop in 2005 at the Oceanographic Museum of Monaco.
Click on this picture to run the main demo (cliquez sur cette image pour voir la demo principale, pour les details voir dessous, ou ecrire a glotin@univ-tln.fr):
Description :
The 3D and 2D demonstrations are given on real deep ocean data from
the Atlantic Undersea Test Center - Bahamas.
These data were distributed for the international benchmark at
the MONACO 2005 workshop. They last 25 minutes, recorded
by bottom mounted hydrophones at -1500 meters,
in the tongue of the ocean - Bahamas - Frequency sample 48 Khz.
Our first reference on multiple whale tracking with results for A and B demonstrations is :
Whales cocktail party: a real-time tracking of multiple whale, by Glotin, Giraudet and Caudal,
in int. Journal Canadian Acoustics, 2008/3, vol 36, 7 pages.
See for more details in our recent published papers (here in annexe) in Eurasip, Ap
plied acoustics, ICASSP... (or ask us for them : glotin@univ-tln.fr)
Comparisons to other systems are available in the bibliography, like for the Naval Undersea Warefare Center in this paper :
Results on the same data set of the Naval Undersea Warefare Center 2006
LINKS TO DEMONSTRATIONS :
A) VIRTUAL REALITY on true recordings, in 3D, of one spermwhale diving in the bahamas sea in 2003 (recordings from NATO):
===============================================================================
A1) 3D whale tracking movie, you listen to the true record that has been used to compute the track that is ploted.
Clic here to see
4D virtual reality representation of true records (12 minutes, .avi, 63Mo)
You can also play a
JAVA version in 3D of this computed track from Bahamas set 2,
, see below to control the camera position
A2) Other animations of the same results
Other demo (from ONCET PIMC_TRACK 2.0) are available in .avi or .flv format, with various hydrophones records, and some particular interesting short samples.
To get these .avi or .flv demo files, load them from the link below, where you also find the VLC.exe player if you need :
FLASH_PLAYER_or_AVI_MOVIES
A3) 3D animated demo on JAVA (set 2 Bahamas, 1 whale) :
An automatic JAVA 3D animation is available at this link :
JAVA 3D animation
A sample view of this animation is given at the top of this page. AMPG movie is available in section A. It is the result of a team work, A. Monnin, J. Pivi...
B) 2D and 3D DEMONSTRATIONS of the Tracking of FOUR WHALES using real NATO records (Bahamas):
==================================================================
You listen to the hydrophone 1 (top right), and you see the four whales (one color for each) moving during 25 minutes.
UpLoad (clic right) or play (clic left) one of these two demo files of ONCET :
B1) The accelerated 2D demo, by 10 times, without sound track :
Fast 2D demo : tracking simultaneously 4 sperm whales (mpeg 6Mo)
Play this demo with a mpeg player.
You'll see the whales moving, one color for each, in the (x,y) plan view.
For the longest demo B2, you listen to the hydrophone 1.
B2) Same as B1, by normal speed, with sound from hydrophone 1 (mp4 format, 29 Mega) :
Full DEMO MPEG4 (~30 Mo)
B3) Same as B2, but in 3D visualisation
using a widows .exe allowing zooms and moves
of the camera.
Load the whole package demo_3d.zip and install it on your Windows system.
Then click on :
"cachalots.exe"
; go to menu "fichier" -> "charger les donnees",
; choose "donnees.txt"
; click the play button...
; read "Aide menu" to get help on how to move the camera
The whales position are given in files
http://glotin.univ-tln.fr/PIMC/DEMO/demo_3d/data/position_baleine_*.txt
one file for each whale.
Format =
t(s) x y z(m) / no confidence level yet
To run these demo click :
