This is a demonstration of the the Video Impairment Detection Mapper (VIDMAP).
The algorithm is described in:

T. Goodall and A. C. Bovik, "Detecting and Mapping Video Impairments"

You can change this program as you like and use it anywhere, but please
refer to its original source (cite our paper and our web page at

========================================================================

VIDMAP is a state-of-the-art detector of many video distortion types and is 
capable of detecting and localizing artifacts without a reference video. 
The same network architecture has been tested with each of the following
distortion types: 
    - Upscaling (Bilinear, Bicubic, Lanczos-4, and Nearest Neighbor)
    - Video Hits (H.264)
    - Video Hits (MPEG2)
    - "False Contours"/Banding
    - H.264 Compression
    - Aliasing
    - Interlacing/Combing
    - Quantization
    - Dropped Frames

Trained weights are included in this archive for full VIDMAP, VIDMAP (2 layer),
and VIDMAP-D (VIDMAP configured to use frame-difference input).

Archive contents and brief description:
    - VIDMAP_train.py         VIDMAP code for training models using
                              generated the hdf5 databases. 

    - VIDMAP_test.py          VIDMAP code for testing trained models 
                              against the hdf5 databases. 

    - VIDMAP_test_whole.py    VIDMAP code for testing trained models 
                              on images and video against the database. 
                              This script outputs a probability of prediction
                              per frame along with a video of predicted frames.

    - single/                 Pretrained data files that correspond to 
                              full VIDMAP version with 3 layers that works
                              on single frames.

    - framediff/              Pretrained data files that correspond to 
                              full VIDMAP version with 3 layers that works
                              on frame differences.

    - 2layer/                 Pretrained data files that correspond to 
                              reduced VIDMAP version with 2 layers that works
                              on single frames (also includes droppedFrames, which
                              required frame differences).

    - datageneration/         Data generation scripts used in VIDMAP paper.

By running each python file without arguments, you will see a printout of 
available options.

Running VIDMAP requires python and the following packages:
    - tensorflow >= 1.10
    - numpy
    - sklearn (for f1 score and mcc metrics)
    - scikit-video
    - h5py (only if you use the generation scripts)
