Function Documentation

distance_transform()

C2DFImage EXPORT_2D distance_transform

(

const C2DImage &

f

)

This function evaluates the 2D distance to a functions defined over a 2D grid If the input function is given as raw data that is not the result of another call to this distance transform function, then one should call distance_transform_prepare to properly prepare the data for the distance transform.

Parameters

[in]

f

the squared values of the function to evaluate the distance to

Returns

distances to the function for each grid point
