We propose an effective two-stage approach to tackle the problem of
language-based Human-centric Spatio-Temporal Video Grounding (HC-STVG) task. In
the first stage, we propose an Augmented 2D Temporal Adjacent Network
(Augmented 2D-TAN) to temporally ground the target moment corresponding to the
given description. Primarily, we improve the original 2D-TAN from two aspects:
First, a temporal context-aware Bi-LSTM Aggregation Module is developed to
aggregate clip-level representations, replacing the original max-pooling.
Second, we propose to employ Random Concatenation Augmentation (RCA) mechanism
during …
