Performing Real-Time Style Transfer with OpenVINO
Introduction
Style transfer is a fascinating technique that allows us to manipulate and generate images in a way that merges the content of one image with the style of another. With OpenVINO, performing real-time style transfer becomes accessible even on regular hardware. In this article, we will dive into the workings of style transfer and explore how OpenVINO can help us achieve impressive results in just a few minutes.
Understanding Style Transfer
Image Representation in Feature Space
At the Core of Generative AI and image manipulation lies the representation of an image in its feature space. Neural networks such as VGG16 are designed to extract the features of an image, creating a representation in the feature or latent space. Similar to transforming an image to the frequency domain, each layer of the network extracts finer grain features, resulting in a representation that captures the image's characteristics.
Extracting Features from Content and Style Images
To perform style transfer, we need to extract the features from both a content image and a style image. While the content features represent the content itself, there are certain style features that indicate the style of the image. By comparing the extracted features, we can build loss functions for both style and content, allowing us to manipulate and generate images that retain recognizable content while adopting the chosen style.
Loss Functions for Style and Content
The loss functions for style and content are essential in guiding the style transfer process. Sufficient content features ensure the image remains recognizable, while an adequate amount of style features ensures the image reflects the chosen style. By optimizing these loss functions, we can achieve impressive style transfer results.
Performing Real-Time Style Transfer with OpenVINO
Setting up Jupyter Notebooks
To experience style transfer firsthand, we can use OpenVINO's jupyter notebooks. Navigating to the OpenVINO notebooks allows us to access a range of ready-to-run notebooks.
