Multi-Modal Three-Stream Network for Action Recognition

8 Sep 2019

Human action recognition in video is an active yet challenging research topic due to high variation and complexity of data.

Deep Concept-wise Temporal Convolutional Networks for Action Localization

26 Aug 2019

In this paper, we empirically find that stacking more conventional temporal convolution layers actually deteriorates action classification performance, possibly ascribing to that all channels of 1D feature map, which generally are highly abstract and can be regarded as latent concepts, are excessively recombined in temporal convolution.

Action recognition with spatial-temporal discriminative filter banks

20 Aug 2019

In this work we focus on how to improve the representation capacity of the network, but rather than altering the backbone, we focus on improving the last layers of the network, where changes have low impact in terms of computational cost.

STM: SpatioTemporal and Motion Encoding for Action Recognition

7 Aug 2019

Spatiotemporal and motion features are two complementary and crucial information for video action recognition.

Two-Stream Video Classification with Cross-Modality Attention

1 Aug 2019

In the experiments, we comprehensively compare our method with two-stream and non-local models widely used in video classification.

Domain-Specific Priors and Meta Learning for Low-shot First-Person Action Recognition

22 Jul 2019

The lack of large-scale real datasets with annotationsmakes transfer learning a necessity for video activity under-standing.

Delving into 3D Action Anticipation from Streaming Videos

15 Jun 2019

Action anticipation, which aims to recognize the action with a partial observation, becomes increasingly popular due to a wide range of applications.

Video Action Classification Using PredNet

14 Jun 2019

In this paper, we evaluate the PredNet \cite{lotter16} on the Something-something action data set \cite{farzaneh18} and implement the PredNet+, which we train in a multi-task fashion to output both classification labels and predictions.

Hallucinating IDT Descriptors and I3D Optical Flow Features for Action Recognition with CNNs

13 Jun 2019

Thus, we propose an end-to-end trainable network with streams which learn the IDT-based BoW/FV representations at the training stage and are simple to integrate with the I3D model.

FASTER Recurrent Networks for Efficient Video Classification

10 Jun 2019

FASTER aims to leverage the redundancy between neighboring clips and reduce the computational cost by learning to aggregate the predictions from models of different complexities.
