Use Case and High-Level Description

Cross-domain correspondence network is an exemplar-based image translation model, consisting of correspondence and translation parts. Model was pre-trained on ADE20k dataset. For details see paper and repository.

Specification

Metric	Value
Type	Image translation
GFLOPs	1080.7032
MParams	167.9141
Source framework	PyTorch*

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.

Metric	Original model	Converted model
PSNR	12.99dB	12.93dB
SSIM	0.34	0.34
IS	13.34	13.35
FID	33.27	33.14

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:
