I just can find the #labeling file? i have gridflow 0.9.4 has it been replaced by some other file??
[#labeling] doesn't have a help file. This external is inside gridflow/base/flow_objects.c , so you just have to load gridflow as a whole ( -lib gridflow ) and you have it.
there's an example patch at http://gridflow.ca/gallery/multiblob.png
[#labeling] has four outlets: outlet 3 gives the amount of pixels in the blob outlet 2 gives a mean vector (where the centre of the blob is) outlet 1 gives a covariance matrix (how much a blob spreads) those outlets are sent to repeatedly for each blob, and then once of: outlet 0 gives an "indexed color" version of the original binary picture by replacing every "1" by the blob number (numbered from 2 upwards).
[#labeling 1] is a variant that has two outlets: outlet 1 gives two-sided "polygons" made of all horizontal segments in a picture. outlet 0 is the same as before, except all blobs are horizontal lines because all scanlines are considered separate.
