Visual-Information-Fidelity (VIF) - Python

This repository contains python implementation of steerable pyramid version of Visual Information Fidelity (VIF) proposed in [1]. This is a replication of MATLAB version released by the authors of [1] which is available HERE.

Dependencies

1) Python (>=3.5)
2) Numpy (>=1.16)
3) Python Imaging Library (PIL) (>=6.0)
4) Steerable Pyramid Toolbox (PyPyrTools) link

Usage

Let imref and imdist denote reference and distorted images respectively. Then the VIF value is calculated as
VIF = vifvec(imref, imdist)

A demo code is provided in test.py for testing purposes
