世界一わかりやすい、stable diffusionのアウトペインティング#ai画像生成 #stablediffusion #ai技術

Alice, an assistant at Aizu Wonderland, introduces the concept of outpainting in image editing, specifically using Stable Diffusion. She discusses recent advancements in technologies like generative filling and AI outpainting, which allow for extending images beyond their original boundaries. Alice aims to share methods and tips for successful outpainting. She acknowledges that there is room for improvement in this technique and invites viewers to provide feedback in the comments. She begins by loading a pre-made image into the 'pnge' tool to demonstrate the process of outpainting.

Alice demonstrates how to outpaint the top part of an image using the 'inpaint' feature in Stable Diffusion. She explains how to adjust the canvas size to extend the image and emphasizes the importance of not clicking within the image before sending it to inpaint. She then shows how to select white color, adjust the brush size, and paint over the black transparent areas to extend the image naturally. Alice also discusses the settings for 'mask content' and 'fill', and the importance of matching the canvas size after adjustments. She sets the denoising strength to 0.6 and randomizes the seed value before generating the image.

Alice continues the outpainting process by working on the lower part of the image. She advises on the importance of not clicking within the image before sending it to inpaint to avoid unintended results. She reviews the process of adjusting the image size and settings, including denoising strength, and emphasizes the need to experiment with different settings to achieve the desired outcome. Alice also introduces the 'Generate Forever' feature, which continuously generates images until stopped, allowing for the creation of multiple images to find the best result. She discusses the selection of a seed value and the use of 'XYZ Plot' to compare different denoising strengths.

Alice concludes the outpainting tutorial by discussing the final adjustments and the use of the 'raw cleaner' tool to remove unwanted elements from the image. She highlights the importance of keeping the denoising strength low to maintain the overall composition of the image. Alice also compares the results of outpainting in Stable Diffusion with that of Photoshop's generative filling, noting the quality and ease of use of both methods. She encourages viewers to try outpainting with Stable Diffusion for its high degree of freedom and creativity.
