Nonlocal and multivariate mathematical morphology

In addition to providing an efficient way to construct a vectorial ordering, nonlocal configurations based on color patches can be easily handled and provide much better results than with classical local ...
The proposed approach is fully unsupervised and consists in constructing a complete lattice from an image as a rank transformation together with a learned ordering of vectors. ...
From this ordering, we can deduce the rank of a vector on the complete lattice L defined as r : R q → [0,m], and construct a rank image as f r :Ω→ [0,m] with f r (p i )=( r • h • f )(p i ) and p i ∈ Ω. ...

The Role of Cytoplasmic Interactions in the Collective Polarization of Tissues and its Interplay with Cellular Geometry
[article]
2018

pre-print
Exploring a phenomenological reaction-diffusion model, we predict a crucial, and novel, role for cytoplasmic interactions in the largescale correlations of cell polarities. ...
We demonstrate that finite-range (i.e. nonlocal) cytoplasmic interactions are necessary and sufficient for the robust and long-range polarization of tissues even in the absence of global cues, and are ...
