AVA: A Video Dataset of Spatio-temporally Localized Atomic Visual Actions

CVPR 2018 tensorflow/models

The AVA dataset densely annotates 80 atomic visual actions in 430 15-minute video clips, where actions are localized in space and time, resulting in 1. 58M action labels with multiple labels per person occurring frequently.

Large-scale weakly-supervised pre-training for video action recognition

CVPR 2019 microsoft/computervision-recipes

Second, frame-based models perform quite well on action recognition; is pre-training for good image features sufficient or is pre-training for spatio-temporal features valuable for optimal transfer learning?

A Closer Look at Spatiotemporal Convolutions for Action Recognition

CVPR 2018 microsoft/computervision-recipes

In this paper we discuss several forms of spatiotemporal convolutions for video analysis and study their effects on action recognition.

BMN: Boundary-Matching Network for Temporal Action Proposal Generation

ICCV 2019 PaddlePaddle/models

To address these difficulties, we introduce the Boundary-Matching (BM) mechanism to evaluate confidence scores of densely distributed proposals, which denote a proposal as a matching pair of starting and ending boundaries and combine all densely distributed BM pairs into the BM confidence map.

BSN: Boundary Sensitive Network for Temporal Action Proposal Generation

ECCV 2018 PaddlePaddle/models

Temporal action proposal generation is an important yet challenging problem, since temporal proposals with rich action content are indispensable for analysing real-world videos with long duration and high proportion irrelevant content.
