Multiple People Tracking by Lifted Multicut and Person Re-identification

Siyu Tang, Mykhaylo Andriluka, Bjoern Andres, Bernt Schiele
2017 2017 IEEE Conference on Computer Vision and Pattern Recognition (CVPR)  
In this work, we propose a novel graphbased formulation that links and clusters person hypotheses over time by solving an instance of a minimum cost lifted multicut problem.  ...  We demonstrate the effectiveness of our formulation by reporting a new state-of-the-art for the MOT16 benchmark. The code and pre-trained models are publicly available 1 .  ...  As shown in Fig. 4 , even beyond 50 frames, the accuracy of our pairwise affinity measure is still above 90%, Such good pairwise affinity should be leveraged into the tracking model.  ...

Margination of White Blood Cells in Microcapillary Flow

Dmitry A. Fedosov, Julia Fornleitner, Gerhard Gompper
2012 Physical Review Letters  
These results are combined in state diagrams, which identify WBC margination for a wide range of flow and cell suspension conditions.  ...  We find WBC margination to be optimal in intermediate ranges of red blood cell (RBC) volume fractions and flow rates, while, beyond these ranges, it is substantially attenuated.  ...  This ''lift-off'' mechanism for the WBC is different from the lift force [19] due to cell-wall hydrodynamic interactions and is governed by the particulate nature of blood.  ...

Mind Your Grip: Even Usual Dexterous Manipulation Requires High Level Cognition

Erwan Guillery, André Mouraux, Jean-Louis Thonnard, Valéry Legrain
2017 Frontiers in Behavioral Neuroscience  
Temporal and dynamic parameters of grip and lift forces were compared across conditions.  ...  The motor task consisted in grasping, lifting and holding an apparatus instrumented with force sensors to monitor motor task performance.  ...  Post hoc comparisons showed that the GF at lift-off was marginally greater in the M + L condition as compared to the M condition (mean ∆ = 0.41 N; t (36) = 2.17; p = 0.04), and significantly greater in  ...
