1. 900260 Automated Visual Event Detection and Classification : JAMSTEC - Toucan Laptop Installation Notes This page last changed on Apr 22, 2010 by dcline. # Toucan ### About Toucan Toucan is the name of the laptop for our JAMSTEC collaborator Dhugal Lindsay. It is intended to be a test platform for JAMSTEC to explore possible uses for AVED. The AVED software suite was installed on this computer by MBARI. Toucan is a ThinkPad Lenova T61p. Fedora Core 8 was installed and configured for this laptop by the Emperor Linux Company http://www.emperorlinux.com/. ### MBARI Network Settings Network settings should be changed per JAMSTEC network configuration. Currently configured as: IP: Dynamically assigned Primary DNS 1 134.89.12.72 Submask 255.255.254.0 Gateway 134.89.12.1 Secondary DNS 2 134.89.12.86 To change these, select the menu Systems->Administration->Network, and change accordingly. ### AVED Installation AVED was installed according to the instructions AVEDac Installation. The AVED software and its dependencies were installed as the user root. Additionally, a user aved was installed to use. Passwords for both the root and aved users have been sent to Dhugal. Two additional steps were required for this installation: Add manual links for the dc1394 control libraries. This was needed to get saliency to compile.
       cd /usr/lib
       ln -s libdc1394.so.22 libdc1394_control.so
       ln -s libdc1394.so.22 libdc1394.so
2. Add /usr/local/lib to the /etc/ld.so.conf. This was needed to get the loader to load the dependent libraries (e.g. xercesc) that are by default installed to /usr/local/lib to load.
       echo /usr/local/lib >> /etc/ld.so.conf
### JAMSTEC Video Data Locations and Processing Scripts Three sets of test high-definition video data were installed on this laptop. Two are sets of still pictures, and one is a video clip. All of this data was provided by JAMSTEC on tape, or digitally. Some basic scripts were provided in addition to the AVED scripts, to give examples of how to process the data. These scripts are noted in the JAMSTEC Scripts table below . For more information on running AVED, please see the AVEDac Running Howto guide.
Directory | Data Type | Process Command
--- | --- | ---
/home/aved/Pictures/benthic/benthic_a | Individual ppm frames from (I think) a PICASSO benthic video recording. Frames were extracted from HD tape. | cd /home/aved/Pictures/benthic/benthic_a jamstec_runmbarivis_displayalg This will display output, similar to the following. *NOTE* Windows display overlapped, not in the cascade pattern shown in this image. Just remember to click and drag them from on top of each other. (click to enlarge) OR jamstec_runmbarivis This will simply spew out the output from mbarivision into the console window.

/home/aved/Pictures/midwater/midwater/midwater_fasttransect | Individual ppm frames from (I think) a PICASSO fast moving midwater video recording. Frames were extracted from a HD tape. | cd /home/aved/Pictures/midwater/midwater/midwater_fasttransect jamstec_runmbarivis or jamstec_runmbarivis_displayalg
/home/aved/Pictures/midwater/midwater/midwater_slowtransect | Individual ppm frames from (I think) a PICASSO slow moving midwater video recording. Frames were extracted from a HD tape. | cd /home/aved/Pictures/midwater/midwater/midwater_slowtransect; jamstec_runmbarivis or jamstec_runmbarivis_displayalg
/home/aved/Video/20080604T063139Z.mov
| Handy Hint This file was named according to the ISO8601 date and time convention as the ISO standard is used by AVED scripts to timestamp events by timecode, instead of frame number. E.g. 20080604T063139Z assumes the tape recording started on 06/06/2008 at 06:31:39 UTC.
| Quicktime movie encoded with mpeg4 codec. Source was received via FTP from Dhugal. | cd /home/aved/Video/20080604T063139Z.mov; jamstec_runprocess 20080604T063139Z.mov
### JAMSTEC Scripts The following are some simple scripts to help get you started:
Script | Description
--- | ---
/home/aved/jamstec_runmbarivis | Simple script that clears the MBARIVISION_OPTIONS variable and runs the mbarivis_command script. Nothing special here - just a wrapper script. Use this to process the benthic_a or midwater_fast/slowtransect images. This must be executed in the root directory of the ppm frames, e.g. /home/aved/Pictures/benthic/benthic_a.
/home/aved/jamstec_runmbarivis_displayalg | Simple script that sets the mbarivision options to display the AVED algorithm output at various stages. This must be executed in the root directory of the ppm frames, Also rescales the input to 640x480 to make the display more manageable.
/home/aved/jamstec_runprocess | Simple wrapper script that executes the runclip AVED script, and displays the output in the vlc viewer. Only processes the first 100 frames of the clip, so remove the argument that specifies the frame range, and by default this will process the entire clip.
