Query: Spatio-Temporal Matching for Siamese Visual Tracking   Similarity matching is a core operation in Siamese trackers. Most Siamese
trackers carry out similarity learning via cross correlation that originates
from the image matching field. However, unlike 2-D image matching, the matching
network in object tracking requires 4-D information (height, width, channel and
time). Cross correlation neglects the information from channel and time
dimensions, and thus produces ambiguous matching. This paper proposes a
spatio-temporal matching process to thoroughly explore the capability of 4-D
matching in space (height, width and channel) and time. In spatial matching, we
introduce a space-variant channel-guided correlation (SVC-Corr) to recalibrate
channel-wise feature responses for each spatial location, which can guide the
generation of the target-aware matching features. In temporal matching, we
investigate the time-domain context relations of the target and the background
and develop an aberrance repressed module (ARM). By restricting the abrupt
alteration in the interframe response maps, our ARM can clearly suppress
aberrances and thus enables more robust and accurate object tracking.
Furthermore, a novel anchor-free tracking framework is presented to accommodate
these innovations. Experiments on challenging benchmarks including OTB100,
VOT2018, VOT2020, GOT-10k, and LaSOT demonstrate the state-of-the-art
performance of the proposed method.
