Index of a point of 3-D digital binary image and algorithm for computing its Euler characteristic

In this work a concept of index of a point of a 3-D (26, 6) digital image is defined. Basing on this concept a new characterization of the so-called simple points [1] as well as an algorithm for computing Euler characteristics of 3-D (26, 6) digital pictures is proposed.In this work a concept of index of a point of a 3-D (26, 6) digital image is defined.
