Hi,
has someone already used cvblob library http://code.google.com/p/cvblob/ with OpenCV4Android?
I've implemented a traffic sign detection and recognition system using cvblob to extract possible sign candidates.
I want to port my implementation to Android via NDK. I do not want to use the OpenCV4Android Java interface.
Best regards.

Finally, cvblobs works with Android NDK! After a few tests with android toolchain and cross compilation I found a
very simple way to port cvblob to Android. I copied all .cpp and .h files from the src folder to the /jni folder of the Android NDK project
and modified the Android.mk
[..]
LOCAL_SRC_FILES := jni_part.cpp cvblob.cpp cvcolor.cpp cvcontour.cpp cvlabel.cpp cvaux.cpp cvtrack.cpp
[..]
and build works!
Unfortunately, after a few frames i get an libc error (Fatal signal 11 (SIGSEV) at 0xdeadbaad).
Possibly a memory error or something like that.
