hello all pd-ers
not quite sure how to hrase this correctly. I need to be able to
dtermine direction of a string of bangs. more sinply, I need to know if they are being triggered in the same direction from which they started, or if they are bing triggered in the opposite. i need positive or negative numbers respectively. stripping what i have to the bone is this:
[ hslider ] [route 1 2 3 4 5 6 7 8] | | | | | | | | o o o o o o o o | [other things] } | } [that give me] } | } -----this stuff is all working well [positive numbers] } | } [independent of direction] } | [number]
I need to be able to tell direction the slider is being "slid" relative to the direction it started from.
hope i am being clear.
many thanks in advance

it looks good, but not working. I have made a fe assumptions in your sketch. does the big X represent the patch chords crossing to opposite inlets? also, i am assuming that the decrease and increase at the bottom are number boxes. with these assumptions, i am getting no change whatsoever in the number boxe at the bottom.
also, before sending this i looked back, connected a number box tot he outlet of [- ] and i am never getting a value above 0, therfore no change is occurring.

so I connected bangs instead of numbers to the bottom under select [0 1] getting bangs for increase and decrease. thank you very much. now is there a way I can get increase or decreases relative to the first direction that takes place? so maybe there could be some reset function and if the slider is on the right side, that way, moving left would be pos. and then moving back to the right could return negative vals.
any ideas?
by the way, i mention this alot but this list ****ing rules.
thank you all so much.

Hi there,
since i am experimenting quite a bit with the mapping- abstractions...in the last days
well, there is many times a solution for problems that i am facing
There is an object called "diff_n" which does simple differentiation,
and thats exactly what you are looking for..
maybe that helps
I have attached a patch...you dont need the mapping-abs in order to
see how its made and how it is working
Cheers Luigi

hi all,
I started a new development for some OpenCV bindigs to PD, I have some
objects working but no time to test or implement newones ...
I want to encourage people to test them and report bugs, features
requests, experiences, etc ... and why not, to help coding ...
Please, note that this is alpha software with known bugs. It runs, and
works at least some of the time, but use at your own risk.... ;) i
mean, probably you will need to fight a bit to get them working ...
but you also will help a lot with feedback
ok, here is the URL : http://hangar.org/wikis/lab/doku.php?id=start:puredata_opencv

This looks very useful. A quick question, do these objects provide
the raw tracking data?
We should get them included in the nightly builds when you are ready
for that, once the 0.40-extended is released.

Looking at things from a more basic level, you can come up with a
more direct solution... It may sound small in theory, but it in
practice, it can change entire economies. - Amy Smith

they provide cool pixel based algorithms like more sophisticated blob operations, pattern recognition methods (like face recognition), and much much more! marius.

yes, can do it.
opencv offers really huge number of functions and algorithms, take a
look here for more info :
http://www.seas.upenn.edu/~bensapp/opencvdocs/ref/opencvref_cv.htm
for now I started with contour detections (and tracking) and yes you
have raw data for them ... however contour detection needs a
prefiltered image to work well, i mean you need to well isolate the
contours you want to track before to use the objects ...
for example pdp_opencv_contours_convexity will send raw info of the
biggest contour detected and can be used (with ann) in pattern
recognition or something like this ...
they provide cool pixel based algorithms like more sophisticated blob operations, pattern recognition methods (like face recognition), and much much more! marius.

(sorry my last mail was incomplete)
hi marius,
today first time I have tried to compile this objects in macosx with
no success ;( but i had gone a little bit far than you ... i think we
are quite close.
first of all overwrite the Makefile you are using by the one i send
attached in this mail. the one you are using is only for linux.
As I saw you had problems with pkg-config I added two new variables in
the Makefile to fit manually with the CFLAGS and LIBS of openCV.
OPENCV_CFLAGS = -I/usr/local/include/opencv OPENCV_LIBS = -L/usr/local/lib -lcxcore -lcv -lhighgui -lcvaux -lml
As we are using the same openCv port I suppose you will not need to
modify them but ensure are correct values for you.
then do:
make clean make
and now the objects will compile with no problem in macosx.
However, when I try to load any of them PD gives me this error::
/Users/lluisgomezbigorda/pix_opencv/pix_opencv_edge.pd_darwin:
dlopen(/Users/lluisgomezbigorda/pix_opencv/pix_opencv_edge.pd_darwin,
10): Symbol not found: __ZN7GemBase10isRunnableEv
Referenced from:
/Users/lluisgomezbigorda/pix_opencv/pix_opencv_edge.pd_darwin
Expected in: dynamic lookup
Seems a problem with the linkage of the library but I'm really a
neewbe in OSX compilations and don't know how to solve it,
maybe someone more experienced in it can put some light here?
thanks in advance, ll.

I got this error too, but only when gem was not loaded. when gem is loaded, everything is fine.
In order to make the opencv objects work I always had to set colorspace RGB. otherwise, I did no see any effect. I think the default on osx is yuv. anyway, will test a little more. great stuff! marius.

yes, this is the eternal colorspace problem ;) ...
openCV works in RGB mode.
As it has good color conversion rutines it's possible to convert all
frames passed as YUV to RGB inside the opencv objects, but this
aproach will be CPU unefficent (specially if you connect some nested
pix_opencv objects).
Anyway thanks for the report I updated online documentation with it.
marius, i have two strange behaviors with pix_opencv (probably bugs
but as my camera don't work with gem i can't test them well), can you
test them and report please ::
1.- strange behavior in pix_opencv_haarcascade, it uses the same code
as pdp_opencv_haarcascade but it doesn?t show the same result.
2.- pix_opencv_contours_boundingrect works only in RGBA pixes?
and ofcourse, as I see you have some experience in CV you will find
lots of features not implemented yet, so make a wishlist please ;)

I already tested it and it was not a bug. it works quite well here.
I have not tested pdp_opencv yet, yesterday I only looked at pix_opencv, I tried to compile pdp_opencv, but again, get errors.

In order to make the opencv objects work I always had to set

yes, the classifier cascade files are the XML's files you have in the
pix_opencv folder, the default ones is haarcascade_frontalface_alt.xml
and it must be in the same folder where you have your "pd_linux" or
"pd_darwin" files.
also the object [pix_opencv_haarcascade] has a message |load $1( to
load any xml file trained as classifier cascades. The default one I'm
using is trained to detect human faces but you can train one to detect
any object you want (it's not easy at all but it's possible).
you can download other "OpenSourced" haarcascades (fer example) here:
here:http://alereimondo.no-ip.org/OpenCV/34
and here you have some info on how to train one: http://note.sonots.com/SciSoftware/haartraining.html

hi jack,
it seems more a problem on colorspace than a opencv one well, there is no line with this message in the pix_opencv code ...
, look at this :
http://lists.puredata.info/pipermail/pd-list/2003-03/010526.html
its a similar message, no?
pix object cannot handle this format (80e0) !
mmmm...

Argghh, I didn't try the objects and they freeze (or sometime

(1234567) ! or [pix_opencv_haarcascade]: ERROR: Could not load classifier cascade Why ? Any idea ?yes, the classifier cascade files are the XML's files you have in
the pix_opencv folder, the default ones is
haarcascade_frontalface_alt.xml and it must be in the same folder
where you have your "pd_linux" or "pd_darwin" files.also the object [pix_opencv_haarcascade] has a message |load $1( to
load any xml file trained as classifier cascades. The default one
I'm using is trained to detect human faces but you can train one to
detect any object you want (it's not easy at all but it's possible).you can download other "OpenSourced" haarcascades (fer example)

I got this error too, but only when gem was not loaded. when gem is loaded, everything is fine.
In order to make the opencv objects work I always had to set colorspace RGB. otherwise, I did no see any effect. I think the default on osx is yuv. anyway, will test a little more. great stuff! marius.

it can mean 2 things.
it _should_ mean, that you send an image in a certain colorspace to the object, which does not know how to deal with this colorspace. (e.g. a YUV image to an RGBA effect; and nobody has coded yet the YUV-part)
however, i believe here it is something different. if your _really_ get "1234567" as the format, then something else is wrong. usually, you should get the openGL colorspace ID here, e.g. "6408" for RGBA). there is no openGL-colorspace "12345678", so this number has to come from somewhere else. it turns out that it is used as a magic number in the GemList. you should never ever see it.
most likely you are trying to compile pix_opencv against a different version of Gem you are using. DO NOT DO THAT!
always make sure to use the same version of Gem for compiling and running, if you don't want to experience any crashes. (especially when using the CVS of Gem, where it might not be obvious that things have changed)
i guess i should introduce a kind of ABI check for 3rd party Gem-externals. but not before the next release.

Thank you lluis! this is very usefull, you know! It was a littlebit hard compile it but ok (path's problems). I'll test it next weeks and try to help you but, what about pdp_v4l2 object that you can find in some of the pdp_opencv help files? with this object i could use finally my (integrated) isight, it should be great! salu2 Husk

you have a patch for the pdp-0.12.5-test-7 sources. adding support
to some v4l2 devices. Actually only tested with a built-in iSight
camera on Ubuntu GNU/Linux.

Hi List ....
there is this well-written "tips and tricks" folder that desribes how
to create objects/abstractions by sending messages.
like...in folder #5: 2.create_new_abstract.pd..
First, thanks to who put that together, this is extremely helpful and
only documented here...
So my question is:
Is there a way to find out the indexnumber of the objects (the
creation-order-number), that is needed for the
| connect a b c d(
message ??
The scenario:
imagine you build many objects and easily want to connect them with a
little counter-like think.
- How do you find out the number that needs to be given to
"connect" ???
Which additional arguments can be send to which object ??
for example i would like to build a number-box, using the built-
in "send" and "recieve" mechanism... Is that possible ???
Thanks

Nope, you need to keep track of those yourself. It really shouldn't be all that hard. I have done a couple of things creating patches in this particular way, and I have found that it is a good idea to put the static objects in a patch first, and then anything that is "variable" would go in next, and then lastly, you wire them up.

Each object is referenced in the order in which they are added to the patch.
- Which additional arguments can be send to which object ??
Not really sure what you mean here, but the string used to create the object should have everything it needs to create that instance.
As far as I know, once you add an object to a patch, the only thing you can do with it is to pass its index to a connect message.
for example i would like to build a number-box, using the built-in "send" and "recieve" mechanism... Is that possible ???
Yes, you just need to set those arguments when you add the objects to the patch. I am not really sure where it is, but there is a listing of each of the objects in PD and what arguments they can handle.
Hope this helped.

Oh yes i found it....
its just in the properties menu of the object - silly me....
