Modelling Simulation and Performance Analysis for Footwear Manufacturing System

2021 Computer Engineering and Intelligent Systems  
In this paper, we present an algorithm for multiple articulated objects tracking based on monocular RGB image sequence.  ...  Fully automatic tracking of articulated motion in real-time with a monocular RGB camera is a challenging problem which is essential for many virtual reality (VR) and human-computer interaction applications  ...  This problem is challenging for many other reasons such as self-similar parts, each articulated object has many degrees of freedom (DOF), occlusion by other objects, and self-occlusion.  ...

Boundary Fragment Matching and Articulated Pose Under Occlusion [chapter]

Nicholas R. Howe
2006 Lecture Notes in Computer Science  
Silhouette recognition can reconstruct the three-dimensional pose of a human subject in monocular video so long as the camera's view remains unoccluded by other objects.  ...  The new method operates without human intervention, and experiments demonstrate that it can reconstruct accurate three-dimensional articulated pose tracks from single-camera walking video despite occlusion  ...  Another body of research has examined the problem of non-articulated object tracking under intermittent occlusion [4, 9] .  ...

Model-based hand tracking with texture, shading and self-occlusions

Martin de La Gorce, Nikos Paragios, David J. Fleet
2008 2008 IEEE Conference on Computer Vision and Pattern Recognition  
A novel model-based approach to 3D hand tracking from monocular video is presented.  ...  The minimization is done efficiently using a quasi-Newton method, for which we propose a rigorous derivation of the objective function gradient.  ...  Monocular hand tracking is even more difficult due to depth ambiguities. Two complementary approaches have been suggested in the literature for monocular hand tracking.  ...

Long-Range Motion Trajectories Extraction of Articulated Human Using Mesh Evolution

Yuanyuan Wu, Xiaohai He, Byeongkeun Kang, Haiying Song, Truong Q. Nguyen
2016 IEEE Signal Processing Letters  
Compared with existing approaches that emphasize temporal consistency of each tracked point, we also consider the spatial structure of tracked points on the articulated human.  ...  Furthermore, we propose an iterative algorithm to efficiently adjust vertices of mesh for a physically plausible deformation, which can meet the local rigidity of mesh and silhouette constraints.  ...  From an alternate point-of-view, N track points are physically belonging to a human undergoing articulated motion.  ...

Predicting 3D People from 2D Pictures [chapter]

Leonid Sigal, Michael J. Black
2006 Lecture Notes in Computer Science  
We propose a hierarchical process for inferring the 3D pose of a person from monocular images.  ...  We demonstrate the method in a laboratory setting where we evaluate the accuracy of the 3D poses against ground truth data. We also estimate 3D body pose in a monocular image sequence.  ...  To simplify the occlusion reasoning as in [21] , we assume that for a given view there is a fixed and known depth ordering of parts.  ...

Contour Based Superquadric Tracking [chapter]

Jaka Krivic, Franc Solina
2003 Lecture Notes in Computer Science  
This paper proposes a technique for tracking a superquadricmodelled object over a monocular video sequences. The object is currently modelled with a single superquadric.  ...  Object's position and orientation in the first frame of the sequence are assumed known. A frame in a sequence is first processed to find object's contour.  ...  Superquadrics are a common building block for modelling articulated objects [1] .  ...

3D Human Motion Tracking and Reconstruction Using DCT Matrix Descriptor

Alireza Behrad, Nadia Roodsarabi
2012 ISRN Machine Vision  
In this work, a new method is proposed for tracking and 3D reconstruction of human motion from the image sequence of a monocular static camera.  ...  In this method, 2D tracking is used for 3D reconstruction, which a database of selected frames is used for the correction of tracking process.  ...  Tracking process may lose the tracked joint for several reasons such as occlusion problem or large distortion. Therefore, the tracked joint information may be incorrect in the current frame.  ...
