template<class T>

void vil3d_max_product_filter ( vil3d_image_view< T > & image,

const vil3d_structuring_element & se,

const vcl_vector< double > & f

) [related]

Preforms raster scan through image, comparing each voxel with nbours.
Runs through every voxel in raster order. Each voxel is compared with weighted versions of offset voxels, and is replaced with the maximum value.
Replace each voxel with max(im(i,j,k),max_a (f[a]*im(i+p_i[a],j+p_j[a],k+p_k[a],plane))
If a suitable combination of se and f is chosen, this performs half an 'exponential distance transform'. For an example of use, see vil3d_exp_distance_transform.
