Sharingan

Sharingan is a tool built on Python 3.6 using OpenCV 3.2 to extract news content as text from newspaper’s photo and perform news context extraction.

For more details and explanation, please refer the blog post here: http://vipul.xyz/2017/03/sharingan-newspaper-text-and-context.html

How it works?

News Extraction

Capture Image

Canny Edge Detection

Dilation

Contour Detection

Contour Approximation and Bound Box

Manual Mode

Context Extraction

The segmentation done above gives the following result after context extraction:

    [‘residential terraces’, ‘busy markets’, ‘Puppies’, ‘inhumane conditions’, ‘popular e-commerce sites’, ‘Sriramapuram’, ‘Russell Market’, ‘issue licences’,
    ‘meeting conditions’, ‘positive impact’, ‘pet owners’, ‘R. Shantha Kumar’, ‘welfare ofﬁcer’, ‘Animal Welfare Board’, ‘India’]
    [‘Kittie’]
    [‘Compassion Unlimited’]
    [‘public spaces’, ‘Animal’, ‘rights activists’, ‘civic body’, ‘Bengaluru’],
    [‘BENGALURU’, ‘Bruhat Bengaluru Mahanagar Palike’, ‘Dane’, ‘English Mastiff’, ‘Bulldog’, ‘Boxer’, ‘Rottweiler’, ‘Bernard’, ‘Shepherd’, ‘Retriever’,
    ‘draft guidelines’, ‘sterilisation’, ‘pet dogs ’, ‘Owners’]

Installation

Installing OpenCV 3.2 from source Python 3.6

wget https://github.com/Itseez/opencv/archive/3.2.0.zip
unzip 3.2.0.zip
cd opencv-3.2.0

mkdir release && cd release

  cmake -DBUILD_TIFF=ON \
      -DBUILD_opencv_java=OFF \
      -DWITH_CUDA=OFF \
      -DENABLE_AVX=ON \
      -DWITH_OPENGL=ON \
      -DWITH_OPENCL=ON \
      -DWITH_IPP=OFF \
      -DWITH_TBB=ON \
      -DWITH_EIGEN=ON \
      -DWITH_V4L=ON \
      -DWITH_VTK=OFF \
      -DBUILD_TESTS=OFF \
      -DBUILD_PERF_TESTS=OFF \
      -DCMAKE_BUILD_TYPE=RELEASE \
      -DBUILD_opencv_python2=OFF \
      -DCMAKE_INSTALL_PREFIX=$(python3.6 -c "import sys; print(sys.prefix)") \
      -DPYTHON3_EXECUTABLE=$(which python3.6) \
      -DPYTHON3_INCLUDE_DIR=$(python3.6 -c "from distutils.sysconfig import get_python_inc; print(get_python_inc())") \
      -DPYTHON3_PACKAGES_PATH=$(python3.6 -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())") ..

The output of above will be similar to this: output
make -j4
make install

Setting up Sharingan

git clone [email protected]:vipul-sharma20/sharingan.git
pip install -r requirements.txt

IMPORTANT: You will require some corpora and trained models for the code to run. You can refer to: http://www.nltk.org/data.html

Interactive Method:

  In [1]: import nltk

  In [2]: nltk.download()

Docker

Try out the code on Jupyter Notebook

docker build -t sharingan-docker .
docker run -p 8888:8888 -it sharingan-docker
