Category: Pd patch Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Ricardo Fabbri (ricardofabbri) Assigned to: Nobody/Anonymous (nobody) Summary: multiblob help improvement Initial Comment: Hi, I documented a crucial limitation about pix_multiblob, namely, that it limits blobs to 10K pixels (e.g. 100x100), since it needs to avoid stack overflow in its recursion-based algorithm. In the attached patch I am also explaining what \"weighted\" means, based on what the sourcecode does. As a workaround to the pix_multiblob limitation, people should be using pix_opencv_floodfill instead. Otherwise the results will be weird for any object greater than 10K pixels in area. ---------------------------------------------------------------------- >Comment By: Ricardo Fabbri (ricardofabbri) Date: 2011-11-11 21:19 Message: I am working on the new implementation; in the meantime, multiblob_help_describe_weighted_rfabbri.patch only describes what weighted means; if you accept this patch we can close this; I will submit the new pix_multiblob implementation on a new patch or through a git repo. ---------------------------------------------------------------------- Comment By: IOhannes m zmölnig (zmoelnig) Date: 2011-11-11 04:31 Message: i think a new implementation would be great, so please go ahead! ---------------------------------------------------------------------- Comment By: Ricardo Fabbri (ricardofabbri) Date: 2011-11-11 00:44 Message: In fact, I could write a stack-based implementation for pix_multiblob, if you agree. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=507081&aid=3436466&group_id=64325 _______________________________________________ GEM-dev mailing list [email protected] http://lists.puredata.info/listinfo/gem-dev
