Method Description:
Objective of multiple object tracking (MOT) is to
assign a unique track identity for all the
objects of interest in a video, across the whole
sequence. Tracking-by-detection is the most
common approach used in addressing MOT problem.
In this work, we propose a method to address MOT
by defining a dissimilarity measure based on
object motion, appearance, structure, and size.
We calculate the appearance and structure-based
dissimilarity measure by matching histograms
following a grid architecture. Motion and size
for each track are predicted using the
information from track’s history. These
dissimilarity values are then used in the
Hungarian algorithm, in the data association step
for track identity assignment. In addition, we
introduce a method to address any false detection
in stable tracks. The proposed method runs in
real time following an online approach. We
evaluate our method in both MOT17 benchmark data-
set for pedestrian tracking and KITTI benchmark
data-set for vehicle tracking using the same
system parameters to verify the robustness of the
proposed method. The method can achieve state-of-
the-art results in both benchmarks.

Detailed Results

From all 29 test sequences, our benchmark computes the HOTA tracking metrics (HOTA, DetA, AssA, DetRe, DetPr, AssRe, AssPr, LocA) [1] as well as the CLEARMOT, MT/PT/ML, identity switches, and fragmentation [2,3] metrics. The tables below show all of these metrics.
