This archive contains a number of off-the-shelf packages. These are covered by their respective licenses.

Instructions

Getting this package set up is not for the faint of heart, it has many dependencies. It also depends on closed-source code which must be obtained from iRobot. See below.

CUDA must be installed at /usr/local/cuda such that /usr/local/cuda/include/ contains the header files.

The CUDA SDK must be installed at /usr/local/NVIDIA_GPU_Computing_SDK/ such that /usr/local/NVIDIA_GPU_Computing_SDK/C/common/inc contains the header files.

The Matlab binary must be in $PATH and it must be a symlink of the form /bin/matlab.

The contents of this archive must be unpacked into your home directory and will create an ~/video-to-sentences-t28feb2012/ directory.

This release relies upon iRobot's implementation of the star detector which cannot be shipped with this archive and must be acquired directly from iRobot. This version must be placed in the install directory before running the installer and named:

irobot_libcudafelz_1.3_alpha_toolkit_3.2_64bit.tar.gz

To install this package first append the contents of dot-bashrc to your .bashrc file

  cat dot-bashrc >>~/.bashrc

and then execute

  ./run

'run' will prompt for root permissions for only one operation before beginning the setup:

  sudo ./packages.sh

This will run a number of

  apt-get install -y

commands to fetch packages which this code depends on.

This code is mostly-self-contained. It will install:

  • an ~/.ffmpeg directory with an ffmpeg preset file required to produce consistent output when rendering video
  • ~/bin/x86_64-Debian, ~/lib/x86_64-Debian, and ~/include/x86_64-Debian which contain the installed Scheme->C and QobiScheme infrastructure
  • ~/darpa-collaboration which contains our codebase

~/darpa-collaboration/ideas contains the code for the video-to-sentences pipeline.

To build the pipeline execute

  darpa-wrap make port
  cd x86_64-Debian
  darpa-wrap make video-to-sentences

in ~/darpa-collaboration/ideas

An example of the pipeline in action is executed at the end of the run script:

darpa-wrap ~/darpa-collaboration/ideas/x86_64-Debian/video-to-sentences\
   -write-object-detector -t 12 -cuda-object-detector -1 -0.1 0.6\
   -cuda-klt -cuda-optical-flow -look-ahead 2\
   -model-path ~/darpa-collaboration/voc4-models/\
   -verbose\
   -event-models-file ~/darpa-collaboration/event-hmms/event-models.text\
   -m person,person-down,person-crouch\
   ~/video-to-sentences-m27feb2012/Chase1_A1_C1_Act1_4_PARK1_ML_MIDD_DARK_4433d840-c5af-11df-bed3-e80688cb869a
