#python-cvblob ##Python Wrapper for the cvblob extension to OpenCV

#python-cvblob is deprecated! Please use the SimpleCV library instead http://simplecv.org it has fast findBlobs() functions!

###2011 Nathan Oostendorp, Ingenuitas Inc. http://ingenuitas.com

This wrapper provides cvBlob's functionality wrappered in a style similar to the native OpenCV python bindings. The function calls are as close as possible to the C++ functions so that you can use the C++ docs/example code.

Conventions are similar to the OpenCV 2.2 python interface, in brief:

• functions: cvFUNCTIONNAME to FUNCTIONAME eg cvRenderBlob -> cvblob.RenderBlob
• data structures: CvDATATYPE to DATATYPE eg cvTrack -> cvblob.Track
• color triples and coordinates are expressed as tuples
• vectors/arrays/lists expressed as python lists
• maps are expressed as python dicts

For examples, look at the test python code.

###Brief install instructions (for OpenCV 2.2, cvBlob 0.10.3, Python 2.6, Boost Python 1.42 under Ubuntu 10.10):

####Step 1: install some prerequisite libraries:

apt-get install build-essential swig gfortran cmake gcc pkg-config libjpeg62-dev libtiff4-dev\
libpng12-dev libopenexr-dev libavformat-dev libswscale-dev liblapack-dev python-dev\
python-setuptools boost-build libboost-all-dev

####Step 2: Download most recent versions of NumPy, OpenCV, and cvBlob

• http://sourceforge.net/projects/numpy/files/NumPy/
• http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/
• http://code.google.com/p/cvblob/

####Step 3: Make NumPy, OpenCV, and cvBlob

#####Numpy:

python setup.py build --fcompiler=gnu95
python setup.py install
python -c 'import numpy; numpy.test()'

#####OpenCV:

mkdir BUILD
cd BUILD
cmake -D CMAKE_BUILD_TYPE=RELEASE -D BUILD_PYTHON_SUPPORT=ON -D WITH_TBB=ON -D CMAKE_INSTALL_PREFIX=/usr ..
make
make install
python -c ‘import cv;’

#####cvBlob:

cmake
make
make install
cd test
../bin/test

#####cvblob-python (from your cvblob directory):

cd cvblob-VERSION/contrib
git clone git://github.com/oostendo/cvblob-python.git python 
cd python/cvblob
./build.sh (you may need to edit if you have a different python than 2.6)
cd ..
python test.py
cp cvblob /usr/lib/python2.6/site-packages (or wherever)

###Todo

• finish tracking and contour wrappers
• wrapper cvRelease* functions
• add cmake or .egg setup ability
• revamp tests as nose tests
