• Title: ObjectAdd: Adding Objects into Image via a Training-Free Diffusion Modification Fashion
• Authors: Ziyue Zhang, Mingbao Lin, Rongrong Ji,
• Abstract summary: We introduce ObjectAdd, a training-free diffusion modification method to add user-expected objects into user-specified area. With a text-prompted image, our ObjectAdd allows users to specify a box and an object, and achieves: (1) adding object inside the box area; (2) exact content outside the box area; (3) flawless fusion between the two areas.

• Abstract: We introduce ObjectAdd, a training-free diffusion modification method to add user-expected objects into user-specified area. The motive of ObjectAdd stems from: first, describing everything in one prompt can be difficult, and second, users often need to add objects into the generated image. To accommodate with real world, our ObjectAdd maintains accurate image consistency after adding objects with technical innovations in: (1) embedding-level concatenation to ensure correct text embedding coalesce; (2) object-driven layout control with latent and attention injection to ensure objects accessing user-specified area; (3) prompted image inpainting in an attention refocusing & object expansion fashion to ensure rest of the image stays the same. With a text-prompted image, our ObjectAdd allows users to specify a box and an object, and achieves: (1) adding object inside the box area; (2) exact content outside the box area; (3) flawless fusion between the two areas

• Improving Text-guided Object Inpainting with Semantic Pre-inpainting [95.17396565347936]
  We decompose the typical single-stage object inpainting into two cascaded processes: semantic pre-inpainting and high-fieldity object generation. To achieve this, we cascade a Transformer-based semantic inpainter and an object inpainting diffusion model, leading to a novel CAscaded Transformer-Diffusion framework.

  We introduce a new task -- enabling explicit control of camera viewpoint for model customization. This allows us to modify object properties amongst various background scenes via text prompts. We propose to condition the 2D diffusion process on rendered, view-dependent features of the new object.

  SwapAnything is a novel framework that can swap any objects in an image with personalized concepts given by the reference. It has three unique advantages: (1) precise control of arbitrary objects and parts rather than the main subject, (2) more faithful preservation of context pixels, (3) better adaptation of the personalized concept to the image.

  Collage Diffusion harmonizes the input layers to make objects fit together. We preserve key visual attributes of input layers by learning specialized text representations per layer. Collage Diffusion generates globally harmonized images that maintain desired object characteristics better than prior approaches.

• Context-Aware Layout to Image Generation with Enhanced Object Appearance [123.62597976732948]
  A layout to image (L2I) generation model aims to generate a complicated image containing multiple objects (things) against natural background (stuff) Existing L2I models have made great progress, but object-to-object and object-to-stuff relations are often broken. We argue that these are caused by the lack of context-aware object and stuff feature encoding in their generators, and location-sensitive appearance representation in their discriminators.
