Add dependencies specs

[Kif11]

I think, it would be useful to attach requirments.txt or Pipfile to this project that one can avoid the burden of manually installing dependencies.

Here is content of my Pipfile that works

[[source]]
name = "pypi"
url = "https://pypi.org/simple"
verify_ssl = true

[dev-packages]

[packages]
numpy = "==1.15.1"
matplotlib = "==2.2.3"
scipy = "==1.1.0"
scikit-image = "==0.14.0"
scikit-learn = "==0.19.2"
imageio = "==2.4.1"
pillow = "==5.2.0"
opencv-python = "*"

[requires]
python_version = "3.7"

Also, looks like you list missing OpenCV dependency. It's a big one :)
