Action Recognition with Actons [PDF]

open access: yes2013 IEEE International Conference on Computer Vision, 2013
With the improved accessibility to an exploding amount of video data and growing demands in a wide range of video analysis applications, video-based action recognition/classification becomes an increasingly important task in computer vision. In this paper, we propose a two-layer structure for action recognition to automatically exploit a mid-level ...

Kernelized covariance for action recognition [PDF]

open access: yes2016 23rd International Conference on Pattern Recognition (ICPR), 2016
In this paper we aim at increasing the descriptive power of the covariance matrix, limited in capturing linear mutual dependencies between variables only. We present a rigorous and principled mathematical pipeline to recover the kernel trick for computing the covariance matrix, enhancing it to model more complex, non-linear relationships conveyed by ...

Viewpoint Manifolds for Action Recognition

open access: yesEURASIP Journal on Image and Video Processing, 2009
Action recognition from video is a problem that has many important applications to human motion analysis. In real-world settings, the viewpoint of the camera cannot always be fixed relative to the subject, so view-invariant action recognition methods are

Video Action Understanding

open access: yesIEEE Access, 2021
Many believe that the successes of deep learning on image understanding problems can be replicated in the realm of video understanding. However, due to the scale and temporal nature of video, the span of video understanding problems and the set of ...

Action recognition by dense trajectories [PDF]

open access: yesCVPR 2011, 2011
Feature trajectories have shown to be efficient for representing videos. Typically, they are extracted using the KLT tracker or matching SIFT descriptors between frames. However, the quality as well as quantity of these trajectories is often not sufficient. Inspired by the recent success of dense sampling in image classification, we propose an approach

HalluciNet-ing Spatiotemporal Representations Using a 2D-CNN

open access: yesSignals, 2021
Spatiotemporal representations learned using 3D convolutional neural networks (CNN) are currently used in state-of-the-art approaches for action-related tasks. However, 3D-CNN are notorious for being memory and compute resource intensive as compared with

View-Invariant Action Recognition [PDF]

open access: yes, 2020
Human action recognition is an important problem in computer vision. It has a wide range of applications in surveillance, human-computer interaction, augmented reality, video indexing, and retrieval. The varying pattern of spatio-temporal appearance generated by human action is key for identifying the performed action.
