In this page, we introduce the Motion Analysis and Re-identification Set (MARS) dataset as well as the baseline evaluation codes. The ECCV paper can be downloaded here [PDF].

MARS (Motion Analysis and Re-identification Set) Dataset




MARS is an extension of the Market-1501 dataset [43]. During collection, we placed six near-synchronized cameras in the campus of Tsinghua university. There were Five 1,080*1920 HD cameras and one 640*480 SD camera. MARS consists of 1,261 different pedestrians whom are captured by at least 2 cameras.

Given a query tracklet, MARS aims to retrieve tracklets that contain the same ID.

New!
We have summarized current state of the art methods on MARS.

Baseline Codes

The baseline evaluation code is provided on Github. Click here.
For each bounding box, we extract the IDE feature described in [1]. We provide the extracted feature below.
IDE Feature (1.92GB) on Baidu,
IDE Feature (1.92GB) on GoogleDrive.

We provide the metric learning codes of XQDA [2] and KISSME [3] using the public codes.

Dataset Download

The dataset package is provided on below.
v2016.08.09 (6.26GB) on Baidu,
v2016.08.09 (6.26GB) on GoogleDrive.

The package contains 2 folders.
1) "bbox_train". There are 509,914 bboxes in this folder, belonging to 625 IDs and 8,298 tracklets.

2) "bbox_test". There are 681.089 bboxes in this folder (gallery+query), belonging to 636 IDs and 12,180 tracklets.


Naming Rule of the bboxes

In bbox "0065C1T0002F0016.jpg", "0065" is the ID of the pedestrian. "C1" denotes the first camera (there are totally 6 cameras). "T0002" means the 2th tracklet. "F016" is the 16th frame within this tracklet. For the tracklets, their names are accumulated for each ID; but for frames, they start from "F001" in each tracklet.

Using the same convention as Market-1501, ID = "00-1" means junk images which do not affect retrieval accuracy; ID = "0000" means distractors, which negatively affect retrieval accuracy.
