2D-TAN

we are hiring talented interns: [email protected]

In this paper, we study the problem of moment localization with natural language, and propose a novel 2D Temporal Adjacent Networks(2D-TAN) method. The core idea is to retrieve a moment on a two-dimensional temporal map, which considers adjacent moment candidates as the temporal context. 2D-TAN is capable of encoding adjacent temporal relation, while learning discriminative feature 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.

News

We extend our 2D-TAN approach to the temporal action localization task and win the 1st place in HACS Temporal Action Localization Challenge at ICCV 2019. For more details please refer to our technical report.
