Abstract

Scalable masks for the selection of angular structures in three-dimensional
(3D) digital images are considered, which are used in processing with a 3D
window sliding over the image and convolved with image fragments.
The model of scalable 3D mask was developed based on expanding smaller mask
along its sides and edges.
In this case, the submatrices remain unchanged, and new elements are added
by repeating the elements of the submatrix, preserving the structure of the corner.
This approach helps to design the hierarchical computations
of 3D data.
