PointTrackV2 presents a new learning strategy for pixel-wise feature learning on the 2D image plane, which has proven to be effective for instance association.

Our network architecture adopts SpatialEmbedding as the segmentation sub-network. The current ranking of PointTrack is available in KITTI leader-board. Until now (07/03/2020), PointTrack++ still ranks first for both cars and pedestrians. The detailed task description of MOTS is avaliable in MOTS challenge.

Getting started

This codebase showcases the proposed framework named PointTrack for MOTS using the KITTI MOTS dataset.

Prerequisites

Dependencies, please refer to 'pt17.yml'

Note that the scripts for evaluation is included in this repo. After images and instances (annotations) are downloaded, put them under kittiRoot and change the path in repoRoot/config.py accordingly. The structure under kittiRoot should looks like:

kittiRoot
│   images -> training/image_02/ 
│   instances
│   │    0000
│   │    0001
│   │    ...
│   training
│   │   image_02
│   │   │    0000
│   │   │    0001
│   │   │    ...  
│   testing
│   │   image_02
│   │   │    0000
│   │   │    0001
│   │   │    ...
