plugin:analysis:density_2d_3d:start

This plugin will compute the density of objects in a image based on distance analysis.

The **NbNeighbors** parameter will determine the number of closest neighbours to compute from each pixel. The distances are sum weighted using this formula :

`∑ (exp(-dist2i * C)`

, with `dist2i`

the squared distance to the ith closest point, and `C = 1/(2*σ*σ`

).

The parameter **radius** is assimilated as σ and determines roughly the radius of *expansion* from the spot centre.

Density computation for the spots in top left, with increasing radius 5, 10 and 15.
