4D Generic Video Object Proposals

Alt text Alt text

This repository contains code, experimental data and oxford-unknown dataset for the work as described in

4D Generic Video Object Proposals (https://arxiv.org/pdf/1901.09260.pdf)

By Aljosa Osep, Paul Voigtlaender, Mark Weber, Jonathon Luiten, Bastian Leibe, Computer Vision Group, RWTH Aachen University

TODO

  • Upload sequences surrounding labeled frames of Oxford Dataset
  • Upload result files
  • Make sure that the uploaded verson of the tracker and configs reproduce the paper results
  • Detailed instructions

Demo Videos

Oxford-unknown dataset

For the labeling process, we manually selected 150 images of the Oxford RobotCar dataset. The subset of images we labeled is available here.

Image sequences are available (temporal neighborhood of the annotated frames) here.

Additional data for sequences (precomputed proposals) are available here.

We labeled 1,494 bounding boxes (1,081 known, 413 unknown) covering the visible portions of objects (non-amodal) by clicking the extremal points.

Known labeled classes (those that overlap with the COCO classes) are car, person, bike and bus. In addition, we labeled several object classes that are not present in the COCO dataset, labeled as unknown objects. Most notable object classes in the unknown set are the following: signage, pole, stone road sign, traffic cone, street sign, rubbish bin, transformer, post box, booth and stroller.

Category Car Person Bike Bus Unknown All
#instances 599 354 78 50 413 1494
Portion 40.1% 23.1% 5.2% 3.3% 27.6% 100%

Baselines

We evaluated the performance of several methods on both known and unknown splits, see our paper for the details. All results will be available for download soon.

Labels

Please find labels in $REPO/eval/oxford_labels. Labels are stored using JSON format. To evaluate recall, use the script $REPO/eval/eval_single_image_proposals.py. To see how to use this script, take a look at $REPO/eval/run_evaluation.sh.

Further instructions and descripton of the label format will be avalible soon. Until then, we recommend to step through eval_single_image_proposals.py script to understand the format.

Prerequisite

  • Proposal evaluation:
    • Python 3.x (for running eval_single_image_proposals.py)
    • pycocotools
    • matplotlib
    • numpy
  • Tracking evaluation (in addition):
    • Python 2.7 (required by tracking evaluation legacy scripts)
    • munkres
    • tabulate

Video Object Proposal Generator (Tracker)

Prerequisite

In order to run the video object proposal generator code, your setup has to meet the following minimum requirements (tested versions in parentheses. Other versions might work, too):

  • cmake (tested with 3.9.6, earlier versions should work too)
  • GCC 5.4.0
  • Libs:
    • Eigen (3.x)
    • Boost (1.55 or later)
    • OpenCV (tested with 3.x, 4.x)
    • PCL (tested on 1.8.0 and 1.9.x) (note: requires FLANN and VTK for the 3D visualizer)

Data

Note: any other paths will do too, you will need to adapt for that in the $REPO/script/exec_tracker.sh

  1. Download KITTI tracking dataset and place it to /home/${USER}/data/kitti_tracking
  2. Download precomputed segmentations we provide for KITTI tracking dataset, unzip to /home/${USER}/data/kitti_tracking/preproc
  3. Clone this repo to /home/${USER}/projects

Compiling the code

  1. mkdir build && cd build
  2. cmake ..
  3. make all

Running the tracker

  1. Enter $REPO/script/
  2. Execute exec_tracker.sh

Tracker execution script settings

  • SEGM_INPUTS - Specify which pre-computed segmentations to use -- Mask Proposal R-CNN (mprcnn_coco; recommended), Sharpmask (sharpmask_coco), Mask R-CNN fine-tuned on KITTI (mrcnn_tuned)
  • INF_MODEL - Specify which model should be used for inference - 4DGVT (recommended) or CAMOT.
  • INPUT_CONF_THRESH - Detection/proposal score threshold. In case it is set to 0.8 or more, you will be only forwarding confident detections.
  • MAX_NUM_PROPOSALS - Max. proposals fed to track generator per frame. More proposals -> slower, higher recall. Not recommended to be set above 500.

Potential Issues

  • In case you want to use self-compiled libs, you may need to specify these paths (e.g., edit CMake cache or use ccmake): PCL_DIR, OpenCV_DIR, BOOST_ROOT
  • CMake Error Unable to find the requested Boost libraries. Unable to find the Boost header files. Please set BOOST_ROOT to the root directory containing Boost or BOOST_INCLUDEDIR to the directory containing Boost's headers. For certain combinations of boost and CMake versions, it may happen CMake will not find all dependencies. Typically this will happen when using newer boost and older CMake; try using the most recent CMake to avoid this issue.
  • I had issues compiling PCL with VTK 9.x, recommending to use VTK 8.x.
