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.
