Silhouette-Edge-Based Descriptor for Human Action Representation and Recognition
Extraction and representation of postures and/or gestures from human activities in videos have been a focus of research in this area of action recognition. With various applications cropping up from different fields, this paper seeks to improve the performance of these action recognition machines by proposing a shape-based silhouette-edge descriptor for the human body. Information entropy, a me...
متن کاملHuman Action Recognition System Based on Silhouette
Abstract—Human action is recognized directly from the video sequences. The objective of this work is to recognize various human actions like run, jump, walk etc. Human action recognition requires some prior knowledge about actions namely, the motion estimation, foreground and background estimation. Region of interest (ROI) is extracted to identify the human in the frame. Then, optical flow tech...
متن کاملHuman Action Recognition: Contour-Based and Silhouette-Based Approaches
Human action recognition in videos is a desired field in computer vision applications since it can be applied in human computer interaction, surveillance monitors, robot vision, etc. Two approaches of features are investigated in this chapter. First approach is a contour-based type. Four features are investigated in this approach such as Cartesian Coordinate Features (CCF), Fourier Descriptors ...
متن کاملSilhouette based human action recognition using PCA and ISOMAP
Human action recognition in computer vision has attracted strong research interest in recent years because of its promising applications. Automated detection of a person‘s atomic movements is called human action recognition. Diverse methods have been proposed for detecting the human action due to the dynamics in the underlying representation of human body. This paper provides a glance over the ...
متن کاملIndependent Viewpoint Silhouette-Based Human Action Modeling and Recognition
This paper addresses the problem of silhouette-based human action modelling and recognition independently of the camera point of view. Action recognition is carried out by comparing a 2D motion template, built from observations, with learned models of the same type captured from a wide range of viewpoints. All these 2D motion templates, are projected into a new subspace by means of the Kohonen ...
