Compact scan mask for 3-D connected components labeling

Connected component labeling is the underlying technique that is typically used in today's digital image processing for both 2-dimensional and 3-dimensional images. This research analyzes the scan mask for connected components labeling and proposes a new scan mask for 3-dimensional connected components labeling operation (26-connectivity), in which the number of pixels to be inspected is reduced from 14 pixels to 8 pixels.
