Method Description:
NC2 adaptive filtering and noise estimation method
are proposed to estimate the process and
measurement noise in real time, so as to improve
the stability and accuracy of tracking. NC2 is a
closed-loop estimation method based on estimation,
calibration and correction, which is different
from the existing adaptive covariance estimation
algorithms. First of all, there are less
restrictions on technical assumptions. It is
assumed that the system is asymptotically stable
rather than observable, and there is no
restriction on the dimensions of the state
transition matrix and the observation matrix.
Secondly, when the process and observation noises
are unknown, the noise covariance can also be
estimated.

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.
