Graph Nearest Neighbors

Lispix draws lines between a blob and its nearest neighbor, using the Label color.

 


Graph N Nearest Neighbors

Lines drawn between each blob and its two nearest neighbors,

Histogram of NN Distances

Histogram of the nearest neighbor distances.

--- graph

--- table

Dialog with default histogram parameters - number of bins, min and max bin values.
More sensible choice of parameters - used for plot above.

 


 

Lists and Tables of Neighbor Distances

All of these tables are text tab-delimited, and can be cut and tasted into spreadsheets.

 

List of NN Distances

Nbrs / List NN Distances

This lists each blob and the distance to its nearest neighbor.  Idx1 and idx2 are the indices of the blobs.  Distances are in pixels.
