I am trying to implement the following research paper on object tracking:
https://www.cv-foundation.org/openaccess/content_cvpr_2013/papers/Li_Learning_Compact_Binary_2013_CVPR_paper.pdf
In the section on hypergraph propagation, the authors have mentioned constructing a hypergraph for modelling the contextual dependencies between adjacent image positions. However, I am not able to understand how exactly has the hypergraph been constructed. Specifically, what are the values of the incidence matrix?
