Hey, This is prolly the noobest question ever but i'm new and dunno how to get around linux that well.
How do i get flow_objects.c from gridflow/base/ running like seen in this link: http://gridflow.ca/gallery/multiblob.png
Thnks, Sisil

flow_objects.c is just a source file containing most builtin object classes of gridflow. you don't use it directly, you run "make" to make gridflow.pd_linux from that file (and from other files all together). Once you have successfully loaded the "gridflow" library in Pd, all builtins are supposed to be available. You shouldn't have any "undefined symbol" error, because if you do, you're sure gridflow.pd_linux is NOT loaded.
almost every gridflow patch is using "flow_objects.c". maybe I shouldn't have mentioned that file in the first place.
please make sure that you have gridflow loading properly at first, perhaps by loading examples/hello-world.pd first, to see whether anything works at all. There's no reason why [#labeling] wouldn't work.
Check the spelling, because I spelt [#labeling] with a single l, instead of the double l such as "labelling" (both exist in english).

Hey, ya, gridflow does work, i tried some examples . so to get the result as shown in : http://gridflow.ca/gallery/multiblob.png(the multiblob patch ) do i have to write the program for it? so is it available somewhere? Sisil.

well, this might seem dumb: but the png you refer to probably shows the entire program you have to write (apart from the erosion subpatch, for which you can probably find an example in the gf help)

Hey, I know its too much to ask but can someone write a .pd file for giving a result as shown in the png (http://gridflow.ca/gallery/multiblob.pnghttp://gridflow.ca/gallery/multiblob.png%28the). I'm juggling 2 internships and college at a time, and after what IOhannes said i saw the prog in the png but had some doubts in places -like in some places its not clear what is connected where(for instance the block with
=25 is connected to sqrt or #labeling or both?) and in the unused stuff:
section theres a block with the symbols (*...*), i''m not sure what that is either.
I would greatly appreciate the help...
Sisil.

I'm finally adding examples/multiblob.pd based on the screenshot of occupants-video.pd found in that screenshot. However I cut out the mask made by [# &] for columns 312-319, because this was specifically for a camera that had a lot of noise in those columns.
I'm also merging in some parts that were never seen, from later versions of the patch (after the screenshot that you know). One of the "new" features is the rotation of the crosses.
I'm also cutting off some useless things from that patch, and I don't just mean the parts marked as "unused", I mean object combinations that were detours that existed only because of the way I made the patch in the first place.
Eventually, I might replace the thresholder by a complete colour detector.
new screenshot at http://gridflow.ca/gallery/multiblob2.png
new patch is at http://gridflow.ca/svn/trunk/examples/multiblob.pd (just use svn update)
I made some changes after making the screenshot: crosses aren't square anymore (change in #make_cross.pd) and the selected areas are now dotted white with some kind of 1/6 stipple.

BTW, take a white wall, shine a bright light all over it diagonally, and not on anything else. walk in front of the wall. you will appear relatively quite dark to the camera.
then use [# <] instead of [# >] to select dark spots instead of bright ones.
