3. Basic Theory of Neural Style Transfer

Before we dive into the technical aspects of neural style transfer, let's first understand the task at HAND. Neural style transfer involves taking two input images: a content image and a style image. The goal is to combine them using a neural network-based transformation and create a composite image that preserves the content of the content image while adopting the artistic style of the style image.

There are two main types of style transfer: artistic style transfer and photo-realistic style transfer. In artistic style transfer, the style image is typically an artistic image, such as a painting or a cartoon. In photo-realistic style transfer, both the content and style images are real images, and the aim is to mimic the style of one image onto the other.

4. Static Image Neural Style Transfer

The first part of this series will focus on static image neural style transfer. In this technique, we transform a single static image by applying the style of another image onto it. This can be achieved using optimization methods like L-BFGS or atom numerical optimizers. These methods allow us to iteratively adjust the pixels of the content image to minimize the difference between the content representation and the style representation.

One popular approach for static image neural style transfer is to use a pre-trained CNN, such as the VGG network. By passing the content and style images through the CNN, we can extract their respective feature maps, which represent the content and style representations of the images. We then aim to minimize the mean squared error (MSE) loss between the feature maps of the generated image and the target style image, while also preserving the content of the content image.

5. Neural Style Transfer Using CNNs

In this part of the series, we will explore neural style transfer using CNNs. Instead of using optimization methods, we can directly plug an image input into a pre-trained CNN and obtain a stylized image as the output. This approach eliminates the need for iterative optimization and makes the style transfer process faster.

Additionally, we will delve into training our own models for neural style transfer. By using transfer learning techniques and training on a dataset of diverse styles, we can create models that can generate stylized images for different artistic styles.

6. Segmentation for Stylizing Specific Portions of an Image

Sometimes you may want to apply style transfer only on specific portions of an image. In this part of the series, we will explore segmentation techniques that allow us to selectively Stylize different regions of an image. By segmenting the image into Meaningful regions, we can apply different styles to each region, creating interesting and artistic effects.

7. Video Style Transfer: Applying on a Per Frame Basis

Moving beyond static images, we will now focus on video style transfer. We will learn how to apply style transfer on a per-frame basis, transforming each frame of a video individually. This approach allows us to create videos with consistent styles throughout, giving them a unique and visually appealing look.

8. Video Style Transfer: Including Temporal Loss

To further enhance video style transfer, we can include temporal loss in our models. Temporal loss helps maintain consistency between consecutive frames in a video, reducing flickering or abrupt changes in the stylized output. By incorporating the Notion of time into our models, we can create more stable and visually pleasing videos.

9. Training Models for Video Style Transfer

In this part of the series, we will focus on training models specifically for video style transfer. We will learn how to Collect and prepare a dataset of video frames, and then train a model that can automatically generate stylized videos. This process involves optimizing the model's parameters to minimize the content loss and style loss across multiple video frames.

10. Using Different Models: Mobile Nets, Efficient Nets, etc.

In the final part of this series, we will explore different models for neural style transfer. We will experiment with models like mobile nets, efficient nets, and other state-of-the-art models to see if they can provide better results. By trying out different architectures and techniques, we can expand our repertoire of styles and create even more impressive stylized images.

11. Conclusion
