Program to extract signatures from documents.

signature-extraction's Issues

Broken requirements.txt because of changes in opencv-contrib library

Describe the bug
Because of patented algorithms like surf and sift being removed from opencv-contrib, installing via the given method in the readme is not working.

To Reproduce
Steps to reproduce the behavior:
Try installing and running the program.

Expected behavior
Opencv-contrib library wont install

How to fix
I installed the following packages in a conda environment one by one and then used a special flag to install opencv-contrib and it worked

Installation - WORKING USING CONDA

Create conda environment with the name 'signature_extraction' and activate virtual env

conda create --name signature_extraction

conda activate signature_extraction

Install packages one by one (requirements.txt not working properly because of different channels)

conda install -c anaconda joblib

conda install -c anaconda numpy

conda install -c anaconda scikit-learn

conda install -c anaconda scipy

conda install -c conda-forge opencv

conda install -c conda-forge threadpoolctl

conda install -c conda-forge tqdm

opencv-contrib package will have to be built from source with NONFREE flag set. If this package installed directly then we wont be able to use a crucial function in the code. This might take some time.

CMAKE_ARGS="-DOPENCV_ENABLE_NONFREE=ON" pip install --no-binary=opencv-contrib-python opencv-contrib-python

Once all packages are installed to the virtual env, cd to the project directory and run the GUI app with

python3 src/extract_gui.py
