Journal ArticleDOI
Three-Dimensional Digital Planes
TL;DR: Definitions of 3-D digital surface and plane are introduced and it is shown that digital convexity is neither a necessary nor a sufficient condition for a digital surface element to be a convex digital plane element.
Journal ArticleDOI
Three-Dimensional Digital Line Segments
TL;DR: It is shown that a digital line segment may be characterized by the chord property holding for its projections onto the coordinate planes, and that a Digital arcs in 3-D digital pictures may not be characterize by its own chord property.
Journal ArticleDOI
Digital Disks
TL;DR: An algorithm is presented that determines whether or not a given digital region is a digital disk.
Journal ArticleDOI
Representation of digital line segments and their preimages
Timothy A. Anderson,Chul E. Kim +1 more
TL;DR: Linear time algorithms are presented which find the nearest support of a 2-D digital line segment, four and eight parameters that represent 2- D and 3-Ddigital line segments, respectively, and construct the complete set of preimages of 1-D and 2-C digital line segments.
Journal ArticleDOI
On the recognition of digital planes in three-dimensional space
Chul E. Kim,Ivan Stojmenovic +1 more
TL;DR: Using the same characterization of digital planes, this work improves the time complexity of the algorithm for deciding whether or not the set is a convex digital plane to O(n2 log n) (while keeping the same memory requirements).
