[Work Log] Sampling - implemeting offline pair candidates
Problem with revamped index-estimation code: it fails miserably on poorly-triangulatable hypotheses.
The heuristic triangulation explodes in size, probably because triangulated points are all over the map (need to confirm this).
Adding error codes; if any part of the pipeline can't complete for any reason, set error code and return. On error, the MCMC move will simply reject the proposal.
Issue with build_full_correspondence: input track is destroyed and replaced.
Refactored to replace make_correspondence with init_track.
make_correspondence -> init_track
make_trivial_correspondence -> init_trivial_corespondence
Running offline_pair_candidates_2. Seems to be running without crashing.
Takes about 10 minutes; seems fast considering all the new logic we've added (re-triangulation, 2D DTW). Probably the mex'd DTW is helping. Some profiling will likely identify some low-hanging optimization fruit here, too.
Need to inspect triangulated curves when done.
Need to see if background subtraction classifier will help prune.
Oops, spoke too soon. Crash at about 75% completion.
Random bug in candidate-proposal generator. wasn't handling the "no candidates" case, resulted in index-out-of-bounds error.
