touchMatrixToMesh

Takes a pointlist with dimensions nd with n point coordinates in d dimensions and a touch matrix of size nn to draw lines from all points to points if the corresponding pixel in the touch matrix is 1.

Parameters

pointlist : Image n*d matrix representing n coordinates with d dimensions. touch_matrix : Image A 2D binary matrix with 1 in pixels (i,j) where label i touches label j. mesh_destination : Image The output image where results are written into.

Categories: Graphs, Visualisation

Availability: Available in Fiji by activating the update sites clij and clij2. This function is part of clij2_-2.5.0.1.jar.
