In this paper, we propose a new sequence-to-sequence learning framework for visual tracking, dubbed SeqTrack. It casts visual tracking as a sequence generation problem, which predicts object bounding boxes in an autoregressive fashion. SeqTrack only adopts a simple encoder-decoder transformer architecture. The encoder extracts visual features with a bidirectional transformer, while the decoder generates a sequence of bounding box values autoregressively with a causal decoder. The loss function is a plain cross-entropy. Such a sequence learning paradigm not only simplifies tracking framework, but also achieves competitive performance on many benchmarks.
In this paper, we propose a new video recognition framework which adapts the pretrained language-image models to video recognition. Specifically, to capture the temporal information, we propose a cross-frame attention mechanism that explicitly exchanges information across frames. To utilize the text information in video categories, we design a video-specific prompting technique which can yield instance-level discriminative textual representation. Extensive experiments demonstrate that our approach is effective and can be generalized to different video recognition scenarios, including fully-supervised, few-shot and zero-shot.
In this paper, we study the problem of moment localization with natural language, and propose a extend our previous proposed 2D-TAN method to a multi-scale version. The core idea is to retrieve a moment from two-dimensional temporal maps at different temporal scales, which considers adjacent moment candidates as the temporal context. The extended version is capable of encoding adjacent temporal relation at different scales, while learning discriminative features for matching video moments with referring expressions. Our model is simple in design and achieves competitive performance in comparison with the state-of-the-art methods on three benchmark datasets.
