Indoor Wireless Signal Modeling with Smooth Surface Diffraction Effects

no code implementations16 Oct 2023 Ruichen Wang, Samuel Audia, Dinesh Manocha

We present a novel algorithm that enhances the accuracy of electromagnetic field simulations in indoor environments by incorporating the Uniform Geometrical Theory of Diffraction (UTD) for surface diffraction.

Towards Language-guided Interactive 3D Generation: LLMs as Layout Interpreter with Generative Feedback

no code implementations25 May 2023 Yiqi Lin, Hao Wu, Ruichen Wang, Haonan Lu, Xiaodong Lin, Hui Xiong, Lin Wang

Generating and editing a 3D scene guided by natural language poses a challenge, primarily due to the complexity of specifying the positional relations and volumetric changes within the 3D space.

Edit Everything: A Text-Guided Generative System for Images Editing

1 code implementation27 Apr 2023 Defeng Xie, Ruichen Wang, Jian Ma, Chen Chen, Haonan Lu, Dong Yang, Fobo Shi, Xiaodong Lin

We introduce a new generative system called Edit Everything, which can take image and text inputs and produce image outputs.

GlyphDraw: Seamlessly Rendering Text with Intricate Spatial Structures in Text-to-Image Generation

3 code implementations31 Mar 2023 Jian Ma, Mingjun Zhao, Chen Chen, Ruichen Wang, Di Niu, Haonan Lu, Xiaodong Lin

Recent breakthroughs in the field of language-guided image generation have yielded impressive achievements, enabling the creation of high-quality and diverse images based on user instructions. Although the synthesis performance is fascinating, one significant limitation of current image generation models is their insufficient ability to generate text coherently within images, particularly for complex glyph structures like Chinese characters.
