Limitations & Future Work
Limitation & Future work We manually annotated each element in the repository, which
took about 2 minutes for each.
Due to the exhaustive search involved in element assembly, our algorithm is still too slow for interactive control.
Our current unification step mainly relies on symmetrization. Thus, the results shown in this paper exhibit similar style of structure.
