Build an Image Style Transfer Tool using CycleGAN
|
Explore how to build an image style transfer tool using CycleGAN in PyTorch. Learn the fundamentals of generative adversarial networks (GANs) and how to apply them for transforming images into different artistic styles.
At a Glance
In this guided project, we will teach you to build a style transfer tool that can “translate” photos into Monet-esque paintings using CycleGAN. We will study the architecture of CycleGAN and then we will build it by breaking it down into multiple parts.
Generative Adversarial Networks, or GANs for short, are a type of deep-learning generative model. A vanilla GAN’s architecture involves two networks: a Generator network for generating new examples and a Discriminator network for classifying examples as real (drawn from the training data) or fake (drawn from the Generator).
GANs typically work with images. Depending on how we set the objective function of a GAN, the Generator can be used to generate new images that satisfy certain rules. In this guided project, we will be learning about CycleGANs, a class of GANs that can be used for transferring the style of images of one domain onto images in another domain by enforcing Cycle Consistency Loss. For instance, a CycleGAN can “translate” the photo of a landscape into a Monet-esque painting of that landscape.
After completing this guided project you will be able to:
- Describe the novelties of CycleGANs compared to traditional GANs.
- Understand the Cycle Consistency Loss and how it’s implemented on images.
- Build the CycleGAN architecture in Keras.
- Gain good practices in training deep learning models.
- Implement a pre-trained CycleGAN for image style transfer tasks.
To complete this guided project, you will need a basic understanding of the working mechanics of neural networks, such as activations, optimizers, loss functions, etc. You will also need some prior experience working with Keras to be able to use its APIs to build, compile and train the CycleGAN. It is also recommended that you have a basic understanding of GANs.
This course mainly uses Python and JupyterLabs. Although these skills are recommended prerequisites, no prior experience is required as this Guided Project is designed for complete beginners.
