Environment:GPU (Python)

Method Description:
We present a simple yet effective quasi-dense
matching method to learn instance similarity from
hundreds of region proposals in a pair
of images. In the resulting feature space, a simple
nearest neighbor search can distinguish different
instances without bells and whistles. We apply our
method to joint object detection and tracking, along
with Faster R-CNN + ResNet50 without using location
or motion heuristics.
Parameters:
See the code for details.

Detailed Results

From all 29 test sequences, our benchmark computes the commonly used tracking metrics CLEARMOT, MT/PT/ML, identity switches, and fragmentations [1,2]. The tables below show all of these metrics.
