replaced -export_dynamic with --export-dynamic and -Wl,--export-dynamic where
appropriate.  It seems that once upon a time -export_dynamic was a real flag.
Now it means -e xport_dynamic, meaning set the entry symbol to xport_dynamic,
giving this error message:

/usr/bin/ld: warning: cannot find entry symbol xport_dynamic; defaulting to 0000000000001b60
updated configure.ac for puredata_openc by ricardofabbri.

better openCV detection.

thanks!

remove useless printf and unused variables
working example
delete old and deprecated .cpp file
safety (?) set all atom to float and 0 before outputing
fix missing #endif statement
take all arguments into account, follow cvblob formatting from pix_opencv_contours
change rot_rect data type
add binarization threshold
