    Evaluating generative models and assessing the quality of generated images is an ongoing research area. In this section, we will explore advanced techniques for evaluating generative models. We will discuss recent advancements in evaluation metrics, such as Fréchet Inception Distance (FID), which measures the distance between the distributions of real and generated images in the feature space. We will also explore perceptual similarity metrics, such as Learned Perceptual Image Patch Similarity (LPIPS), which quantify the perceptual similarity between images. Additionally, we will discuss the challenges in evaluating generative models objectively and the importance of combining quantitative and qualitative evaluation methods.
  5. Application Areas:
    Generative models and image synthesis have found applications in a wide range of fields. In this section, we will explore advanced application areas of generative models. We will discuss the use of generative models for image editing tasks, such as image inpainting, style transfer, and image morphing. We will delve into advanced techniques for controllable image synthesis, including conditional generation and attribute manipulation. Moreover, we will explore the use of generative models in the field of fashion and design, where they have been used for virtual try-on, garment generation, and personalized fashion recommendations.
