Model overview

diffae is an AI model for image manipulation developed by Konpat Preechakul, Nattanat Chatthee, Suttisak Wizadwongsa, and Supasorn Suwajanakorn. It is based on their research paper "Diffusion Autoencoders: Toward a Meaningful and Decodable Representation" which was presented at CVPR 2022. The model builds on Stable Diffusion by using a diffusion autoencoder to learn a more meaningful and decodable latent representation, enabling controllable image manipulation.

Model inputs and outputs

diffae takes an input image and allows for targeted manipulation along various semantic attributes, such as adding bangs, eyeglasses, or changing hairstyles. The key inputs are the original image, the target manipulation class, and the desired manipulation amplitude. The model then outputs the manipulated image.

Inputs

  • image: The input image to be manipulated. The image will be aligned and cropped before processing.
  • target_class: The semantic attribute to be modified, such as "Bangs", "Eyeglasses", or "Wavy Hair".
  • manipulation_amplitude: The strength of the desired manipulation, from -0.5 to 0.5.
  • T_step: The number of steps to use for the image generation process, with a default of 100.
  • T_inv: The number of steps to use for the inversion process, with a default of 200.

Outputs

  • Array of manipulated images: The model outputs an array of manipulated images, with the target attribute adjusted based on the provided inputs.

Capabilities

diffae is capable of performing high-quality, semantic-aware image manipulation on faces. Unlike simple attribute editing, diffae can seamlessly blend the target attribute with the original image, producing natural-looking results. The model has been trained on the FFHQ, Bedroom, and Horse datasets, allowing for manipulation of a variety of image types.

What can I use it for?

diffae can be a powerful tool for content creation, photo editing, and creative exploration. By enabling targeted modifications to facial attributes, the model can be used to experiment with different styles, hairstyles, or accessories on portraits and selfies. This can be useful for applications like virtual try-on, photo editing, and social media content generation.

Things to try

One interesting aspect of diffae is its ability to perform latent-space manipulation, where changes are made directly to the model's internal representation of the image. This can lead to more nuanced and seamless modifications compared to traditional image editing techniques. Users can experiment with different manipulation amplitudes to find the right balance of change and preservation of the original image.

Model inputs and outputs The latent-diffusion-text2img model takes a text prompt as input and generates an image as output. The text prompt can describe a wide range of subjects, from realistic scenes to abstract concepts, and the model will attempt to generate a corresponding image. Inputs Prompt**: A text description of the desired image. Seed**: An optional seed value to enable reproducible sampling. Ddim steps**: The number of diffusion steps to use during sampling. Ddim eta**: The eta parameter for the DDIM sampler, which controls the amount of noise injected during sampling. Scale**: The unconditional guidance scale, which controls the balance between the text prompt and the model's own prior. Plms**: Whether to use the PLMS sampler instead of the default DDIM sampler. N samples**: The number of samples to generate for each prompt. Outputs Image**: A high-resolution image generated from the input text prompt. Capabilities The latent-diffusion-text2img model is capable of generating a wide variety of photo-realistic images from text prompts.

repaint is an AI model for inpainting, or filling in missing parts of an image, using denoising diffusion probabilistic models. It was developed by cjwbw, who has created several other notable AI models like stable-diffusion-v2-inpainting, analog-diffusion, and pastel-mix. The repaint model can fill in missing regions of an image while keeping the known parts harmonized, and can handle a variety of mask shapes and sizes, including extreme cases like every other line or large upscaling. Model inputs and outputs The repaint model takes in an input image, a mask indicating which regions are missing, and a model to use (e.g. CelebA-HQ, ImageNet, Places2). It then generates a new image with the missing regions filled in, while maintaining the integrity of the known parts. The user can also adjust the number of inference steps to control the speed vs. quality tradeoff. Inputs Image**: The input image, which is expected to be aligned for facial images. Mask**: The type of mask to apply to the image, such as random strokes, half the image, or a sparse pattern. Model**: The pre-trained model to use for inpainting, based on the content of the input image. Steps**: The number of denoising steps to perform, which affects the speed and quality of the output. Outputs Mask**: The mask used to generate the output image. Masked Image**: The input image with the mask applied. Inpaint**: The final output image with the missing regions filled in. Capabilities The repaint model can handle a wide variety of inpainting tasks, from filling in random strokes or half an image, to more extreme cases like upscaling an image or inpainting every other line. It is able to generate meaningful and harmonious fillings, incorporating details like expressions, features, and logos into the missing regions. The model outperforms state-of-the-art autoregressive and GAN-based inpainting methods in user studies across multiple datasets and mask types. What can I use it for? The repaint model could be useful for a variety of image editing and content creation tasks, such as: Repairing damaged or corrupted images Removing unwanted elements from photos (e.g. power lines, obstructions) Generating new image content to expand or modify existing images Upscaling low-resolution images while maintaining visual coherence By leveraging the power of denoising diffusion models, repaint can produce high-quality, realistic inpaintings that seamlessly blend with the known parts of the image. Things to try One interesting aspect of the repaint model is its ability to handle extreme inpainting cases, such as filling in every other line of an image or upscaling with a large mask. These challenging scenarios can showcase the model's strengths in generating coherent and meaningful fillings, even when faced with a significant amount of missing information. Another intriguing possibility is to experiment with the number of denoising steps, as this allows the user to balance the speed and quality of the inpainting. Reducing the number of steps can lead to faster inference, but may result in less harmonious fillings, while increasing the steps can improve the visual quality at the cost of longer processing times. Overall, the repaint model represents a powerful tool for image inpainting and manipulation, with the potential to unlock new creative possibilities for artists, designers, and content creators.
