fast-neural-style-mosaic-onnx

Use Case and High-Level Description

The fast-neural-style-mosaic-onnx model is one of the style transfer models designed to mix the content of an image with the style of another image. The model uses the method described in Perceptual Losses for Real-Time Style Transfer and Super-Resolution along with Instance Normalization. Original ONNX models are provided in the repository.
