Learning Long-Term Spatial-Temporal Graphs for Active Speaker Detection

ECCV 2022poster

"Active speaker detection (ASD) in videos with multiple speakers is a challenging task as it requires learning effective audiovisual features and spatial-temporal correlations over long temporal windows. In this paper, we present SPELL, a novel spatial-temporal graph learning framework that can solv…

Exploiting Transitivity for Learning Person Re-Identification Models on a Budget

CVPR 2018poster

Minimization of labeling effort for person re-identification in camera networks is an important problem as most of the existing popular methods are supervised and they require large amount of manual annotations, acquiring which is a tedious job. In this work, we focus on this labeling effort minimiz…

Incorporating Scalability in Unsupervised Spatio- Temporal Feature Learning

ICASSP 2018accepted

Deep neural networks are efficient learning machines which leverage upon a large amount of manually labeled data for learning discriminative features. However, acquiring substantial amount of supervised data, especially for videos can be a tedious job across various computer vision tasks. This neces…

W-TALC: Weakly-supervised Temporal Activity Localization and Classification

ECCV 2018poster

Most activity localization methods in the literature suffer from the burden of frame-wise annotation requirement. Learning from weak labels may be a potential solution towards reducing such manual labeling effort. Recent years have witnessed a substantial influx of tagged videos on the Internet, whi…
