1st Workshop on

Target Re-Identification and
Multi-Target Multi-Camera Tracking

In conjunction with CVPR 2017
July 2017, Honolulu

This workshop brings together researchers from two subfields of computer vision that have seen growing activity in the past few years: Target Re-Identification (ReID) and Multi-Target Multi-Camera Tracking (MTMCT). This workshop explores opportunities for cross-fertilization between these two thriving and important subfields of computer vision and aims to deepen discussions on future directions.

Call for papers

This one day workshop will host invited speakers, poster sessions and oral presentations. We encourage authors to explore pollination between the fields of ReID and MTMCT and take on research questions, rather than just obtaining state-of-the-art results on benchmarks. Examples of such questions are:

Problem definitions and motivation

Let a query be an image that tightly bounds a single instance of a target of interest (people, vehicles, etc.). Assume that a gallery contains images of several targets in this format as well as distractor images with arbitrary content. Target re-identification retrieves all and only the gallery images of the same target as the query.

Given a set of videos taken by multiple cameras, multi-target multi-camera tracking places tight bounding boxes around all targets in the videos and partitions the boxes into sets called trajectories. A trajectory is the set of all boxes that bound a unique target, ordered by time.

These two problems are clearly different. However, they share several common aspects as well. Here, you can find some of the (dis)similarities that we could think of. Can you come up with more?


To submit a new paper to the workshop, you have to do so through the CMT website. The workshop paper submissions should be in the same format as the main conference. Please refer to the CVPR 2017 author guidelines for more details.
