Accuracy#

Metrics were calculated between generated images by model and real validation images from ADE20k dataset. For some GAN metrics (IS and FID) you need to use classification model as verification network. In our case it is Inception-V3 model. For details, please check Accuracy Checker config <omz_dir>/models/public/cocosnet/accuracy-check-pipelined.yml.

Inputs#

  1. name: input_seg_map, shape: 1, 151, 256, 256 - Input semantic segmentation mask (one-hot label map) in the format B, C, H, W, where:

    • B - batch size

    • C - number of classes (151 for ADE20k)

    • H - mask height

    • W - mask width

  2. name: ref_image, shape: 1, 3, 256, 256 - An reference image (exemplar) in the format B, C, H, W, where:

    • B - batch size

    • C - number of channels

    • H - image height

    • W - image width

    Expected color order is BGR (At original model expected color order is RGB).

  3. name: ref_seg_map, shape: 1, 151, 256, 256 - A mask (one-hot label map) for reference image in the format B, C, H, W, where:

    • B - batch size

    • C - number of classes (151 for ADE20k)

    • H - mask height

    • W - mask width

Output#

Image, name: exemplar_based_output, shape: 1, 3, 256, 256 - A result (generated) image based on exemplar in the format B, C, H, W, where:

  • B - batch size

  • C - number of channels

  • H - image height

  • W - image width

Output color order is RGB.

Download a Model and Convert it into OpenVINO™ IR Format#

You can download models and if necessary convert them into OpenVINO™ IR format using the Model Downloader and other automation tools as shown in the examples below.

An example of using the Model Downloader:

omz_downloader --name <model_name>

An example of using the Model Converter:

omz_converter --name <model_name>

Demo usage#

The model can be used in the following demos provided by the Open Model Zoo to show its capabilities:
