asmlib-opencv

This repo is a fork of https://code.google.com/p/asmlib-opencv/ to demonstrate how 3rd party C++ modules can be integrated into the Python bindings for OpenCV. This code depends on opencv/opencv#1571.

Build instructions

The following lines are copy-and-pastable instructions to build the OpenCV branch in the Pull Request above and this repository.

Build OpenCV branch

This will download and build the code from the dependant branch and then install it into a temporary directory.

git clone https://github.com/derfred/opencv.git opencv_external
cd opencv_external
git checkout external_python_modules
mkdir build
cd build
cmake -D CMAKE_INSTALL_PREFIX=../../opencv_external_install ..
make
make install

On my machine (MacOS Mountain Lion with Python installed via homebrew) I had to specify the Python executable. Should you have problems building, try the following changes to the cmake line:

cmake -D CMAKE_INSTALL_PREFIX=../../opencv_external_install -D PYTHON_EXECUTABLE=/usr/local/bin/python -D PYTHON_INCLUDE_DIR=/usr/local/Cellar/python/2.7.4/Frameworks/Python.framework/Headers -D PYTHON_LIBRARY=/usr/local/Cellar/python/2.7.4/Frameworks/Python.framework/Versions/2.7/lib/libpython2.7.dylib ..

Build ASMLib (this repository)

git clone https://github.com/derfred/asmlib-opencv.git
cd asmlib-opencv/src
mkdir build
cd build
OpenCV_DIR=../../../opencv_external_install/share/OpenCV/ cmake ..
make

Run the demo

If you have followed the steps above then the following will run the Python demo on your webcam, assuming your CWD is src/demo.

PYTHONPATH="../build/lib:$PYTHONPATH" python demo.py -f -pc -m ../../data/muct76.model -C ../../data/haarcascade_frontalface_alt.xml
