Kinematic skeleton graph augmented network for human parsing

Neurocomputing, 2020
Abstract Human parsing, which is a task of labeling pixels in human images into different fine-grained semantic parts, has achieved significant progress during the past decade. However, there are still several challenges in human parsing, due to occlusions, varying poses and similar appearance between the left/right parts. To tackle these problems, a

Isomorphism Identification of Graphs of Kinematic Chains

Volume 8: 31st Mechanisms and Robotics Conference, Parts A and B, 2007
Isomorphism identification of graphs is one of the most important and challenging problems in the fields of mathematics, computer science and mechanisms. This paper attempts to solve the problem by finding a unique representation of graphs. First, the perimeter loop of a graph is identified from all the loops of the graph obtained through a new ...

Logical Foundations of Kinematic Chains: Graphs, Line Graphs, and Hypergraphs

Journal of Mechanical Design, 1990
In terms of concepts from the theory of graphs and hypergraphs we formulate a precise structural characterization of a kinematic chain. To do this, we require the operations of line graph, intersection graph, and hypergraph duality. Using these we develop simple algorithms for constructing the unique graph G (KC) of a kinematic chain KC and (given an ...

Kinematic Reeb Graph Extraction Based on Heat Diffusion

2014 22nd International Conference on Pattern Recognition, 2014
This paper presents a new approach of Reeb graph extraction adapted to 3D dynamic triangular Meshes. Particularly, we propose a new continuous scalar function, used for Reeb graph construction. This function is based on the heat diffusion properties. The restriction of the heat kernel to temporal domain makes the scalar function intrinsic and stable ...

Multi-part kinematic constraint prediction for automatic generation of CAD model assemblies using graph convolutional networks

CAD Computer Aided Design
This paper presents a machine learning-based approach to predict kinematic constraints between CAD models that have potentially never been assembled together before.

Variation, Kinematics and Further Graphs

1979
Variation in mathematics is the study of the interdependence of variables. For instance, in the formula obtained for simple interest in chapter 2 (volume 1) $$I = \frac{{PRT}}{{100}}$$ the interest ‘varies’ as the principal P, the rate R and the time T. If any one of these quantities changes, then the interest changes.

Exoskeleton systems kinematics analysis with graph-matroid approach

2011 IEEE International Conference on Automation Science and Engineering, 2011
This paper presents a novel technique for the kinematic analysis of exoskeleton systems, based on incidence matrices in an edge-oriented graph. Kinematic equations are generated in matrix form using a base of circuits from a cycle matroid. This set of independent equations, automatically generated due to matrix orthogonalities, allows efficient ...

Students' reading images in kinematics: The case of real-time graphs

International Journal of Science Education, 2002
Graphs of real-time experiments are useful tools in science education; their intrinsic features allow innovative didactic approaches. The use of such images is spreading and is likely to become common classroom practice. This paper describes a study in which secondary school students were called upon to read and interpret documents containing images of
