Detection and Tracking of Humans by Probabilistic Body Part Assembly [PDF]

Procedings of the British Machine Vision Conference 2005, 2005
This paper presents a probabilistic framework of assembling detected human body parts into a full 2D human configuration. The face, torso, legs and hands are detected in cluttered scenes using boosted body part detectors trained by AdaBoost. Body configurations are assembled from the detected parts using RANSAC, and a coarse heuristic is applied to ...

Towards revealing the global diversity and community assembly of soil eukaryotes.

Ecology Letters, 2021
Soil fungi, protists, and animals (i.e., the eukaryome) play a critical role in key ecosystem functions in terrestrial ecosystems. Yet, we lack a holistic understanding of the processes shaping the global distribution of the eukaryome.

Design and Simulation of On-Orbit Assembly System Based on Insect-Inspired Transportation

Biomimetics, 2023
In response to the requirements of large-scale space in-orbit assembly and the special environment of low gravity in space, this paper proposes a small robot structure with the integration of assembly, connection, and vibration reduction functionalities.

A Tolerance Type Screening Method Based on Similarity Evaluation

Applied Sciences
In the context of automatic generation methods for tolerance specifications, the current approach entails designers subjectively selecting geometric tolerances suitable for annotation from the tolerance types generated through automatic reasoning.

A Tolerance Specification Automatic Design Method for Screening Geometric Tolerance Types

Applied Sciences
At present, the automatic generation of tolerance types based on rule-based reasoning has an obvious characteristic: for the same assembly feature, tolerance items are recommended that satisfy all feature characteristics, with a large number of ...

Multi-robot spot-welding cells for car-body assembly

, 2017
Multi-robot cells for spot welding use coordinated robots to assemble metal panels via spot welding by coordinated robots, for instance in the construction of car doors.

RNA transcription modulates phase transition-driven nuclear body assembly

Proceedings of the National Academy of Sciences of the United States of America, 2015
Significance Living cells contain various membraneless organelles whose size and assembly appear to be governed by equilibrium thermodynamic phase separation. However, the dynamics of this process are poorly understood.

Export of piRNA precursors by EJC triggers assembly of cytoplasmic Yb-body in Drosophila

Nature Communications, 2016
PIWI-interacting RNAs (piRNAs) are effectors of transposable element (TE) silencing in the reproductive apparatus. In Drosophila ovarian somatic cells, piRNAs arise from longer single-stranded RNA precursors that are processed in the cytoplasm presumably

The DDX6–4E-T interaction mediates translational repression and P-body assembly

Nucleic Acids Research, 2016
4E-Transporter binds eIF4E via its consensus sequence YXXXXLΦ, shared with eIF4G, and is a nucleocytoplasmic shuttling protein found enriched in P-(rocessing) bodies. 4E-T inhibits general protein synthesis by reducing available eIF4E levels.

Diversity-triggered deterministic bacterial assembly constrains community functions

Nature Communications, 2019
A growing body of evidence suggests that microbial α-diversity (local species richness) may have positive effects on ecosystem function. However, less attention has been paid to β-diversity (the variation among local microbial assemblages).
