Branch Collapsing is a fundamental skeletonization technique; the improvements over the branch trimming that Skelebrator brings to the table are primarily a matter of flexibility, efficiency, and usability. The branch trimming method utilized by other automated skeletonization applications allows a limited range of removal criteria; in some cases, just elevation and length. Workarounds are required if another removal criteria is desired, resulting in more steps to obtain the desired results.

Conversely, Skelebrator innately provides a wide range of removal criteria, increasing the scope of this skeletonization step and eliminating the need for inefficient manual workarounds.

The following diagrams illustrate the results of Branch Collapsing;
