build](https://img.shields.io/docker/automated/vipul20/sharingan.svg)]()\n\nSharingan is a tool built on Python 3.6 using OpenCV 3.2 to extract news\ncontent as text from newspaper’s photo and perform news context extraction.\n\nFor more details and explanation, please refer the blog post here: [http://vipul.xyz/2017/03/sharingan-newspaper-text-and-context.html](http://www.vipul.xyz/2017/03/sharingan-newspaper-text-and-context.html)\n\nHow it works?\n=============\n\nNews Extraction\n---------------\n\n\u003cp align=\"center\"\u003e\n    \u003cb\u003eCapture Image\u003c/b\u003e\n\u003c/p\u003e\n\n![Alt](https://i.imgur.com/6DklnQt.jpg)\n\n\u003cp

\"drag\")\n\n![Alt](https://cdn-images-1.medium.com/max/1600/1*_pOvzvVLvHvcgrpxQL9XeA.gif \"thresh\")\n\nContext Extraction\n------------------\n\nThe segmentation done above gives the following result after context extraction:\n\n        [‘residential terraces’, ‘busy markets’, ‘Puppies’, ‘inhumane conditions’, ‘popular e-commerce sites’, ‘Sriramapuram’, ‘Russell Market’, ‘issue licences’,\n        ‘meeting conditions’, ‘positive impact’, ‘pet owners’, ‘R. Shantha Kumar’, ‘welfare officer’, ‘Animal Welfare Board’, ‘India’]\n        [‘Kittie’]\n        [‘Compassion Unlimited’]\n        [‘public spaces’, ‘Animal’, ‘rights activists’, ‘civic body’, ‘Bengaluru’],\n        [‘BENGALURU’, ‘Bruhat Bengaluru Mahanagar Palike’, ‘Dane’, ‘English Mastiff’, ‘Bulldog’, ‘Boxer’, ‘Rottweiler’, ‘Bernard’, ‘Shepherd’, ‘Retriever’,\n        ‘draft guidelines’, ‘sterilisation’, ‘pet dogs ’, ‘Owners’]\n\n\nInstallation\n============\n\nInstalling OpenCV 3.2 from source Python 3.6\n--------------------------------------------\n\n* `wget https://github.com/Itseez/opencv/archive/3.2.0.zip`\n* `unzip 3.2.0.zip`\n* `cd opencv-3.2.0`\n* `mkdir release \u0026\u0026 cd release`\n\n        cmake -DBUILD_TIFF=ON \\\n            -DBUILD_opencv_java=OFF \\\n            -DWITH_CUDA=OFF \\\n            -DENABLE_AVX=ON \\\n            -DWITH_OPENGL=ON \\\n            -DWITH_OPENCL=ON \\\n            -DWITH_IPP=OFF \\\n            -DWITH_TBB=ON \\\n            -DWITH_EIGEN=ON \\\n            -DWITH_V4L=ON \\\n            -DWITH_VTK=OFF \\\n            -DBUILD_TESTS=OFF \\\n            -DBUILD_PERF_TESTS=OFF \\\n            -DCMAKE_BUILD_TYPE=RELEASE \\\n            -DBUILD_opencv_python2=OFF \\\n            -DCMAKE_INSTALL_PREFIX=$(python3.6 -c \"import sys; print(sys.prefix)\") \\\n            -DPYTHON3_EXECUTABLE=$(which python3.6) \\\n            -DPYTHON3_INCLUDE_DIR=$(python3.6 -c \"from distutils.sysconfig import get_python_inc; print(get_python_inc())\") \\\n            -DPYTHON3_PACKAGES_PATH=$(python3.6 -c \"from distutils.sysconfig import get_python_lib; print(get_python_lib())\") ..\n\n* The output of above will be similar to this: [output](https://gist.github.com/vipul-sharma20/d57a779619f22b2254b66c89c957faf2)\n* `make -j4`\n* make install\n\nSetting up Sharingan\n--------------------\n\n* `git clone git@github.com:vipul-sharma20/sharingan.git`\n* `pip install -r requirements.txt`\n\n**IMPORTANT:** You will require some corpora and trained models\nfor the code to run. You can refer to: [http://www.nltk.org/data.html](http://www.nltk.org/data.html)\n\n* Interactive Method:\n\n        In [1]: import nltk\n\n        In [2]: nltk.download()\n\nDocker\n======\n\nTry out the code on Jupyter Notebook\n\n* `docker build -t sharingan-docker .`\n* `docker run -p 8888:8888 -it sharingan-docker`\n\nThanks to\n=========\n\nI am no wizard.
