hey everyone,

I was playing with the pix_opencv_hu_compare because I figure that it's the best way to track and detect a picture in a card. But then I got the error message:

[pix_opencv_threshold]: pix_opencv_threshold : yuv format not supported
error: [pix_opencv_hu_compare] : no method to combine (YUV) and (RGBA)

do you know why is it?

Thanks a lot :)

ola yves,

ookay, i'll try that, even though i did try to go back to pd-extended 0.41-4, and yeah your opencv works :) but i'll try your suggestion anyway :D

Anyway, i Was wondering, what is the best way to implement blob detection on pd? or if I want to detect and track an edge of an object from a camera, what is the best way to do it?

Thank you

Regards,

didit

ola,

hum, get sure you've got something here:
/Library/Frameworks/OpenCV.framework/Headers/

and that you installed the target pd-extended too in :
/Applications/Pd-extended.app/Contents/Resources/include/

it should work then

saludos,
sevy

hi there,

i was compiling puredata_opencv this morning for a school project. however, i got this error while trying to compile it:

configure: error: you need to install opencv library (libcv)

i already followed all the sequence of compiling it. I'm on a Mac, so I already put the opencv framework on /Library/Frameworks folder, and I already downloaded the pd 0.42.5 and Gem 0.92.3, because i'm using the latest pd-extended.

any suggestion why is this happening? Or should I just use the previous pd-extended so that I can use the available packages of puredata_opencv?

Thank you very much for any help :)
