Palette: Image-to-Image Diffusion Models [PDF]
International Conference on Computer Graphics and Interactive Techniques, 2021 This paper develops a unified framework for image-to-image translation based on conditional diffusion models and evaluates this framework on four challenging image-to-image translation tasks, namely colorization, inpainting, uncropping, and JPEG ...

Human Motion Diffusion Model [PDF]
International Conference on Learning Representations, 2022 Natural and expressive human motion generation is the holy grail of computer animation. It is a challenging task, due to the diversity of possible motion, human perceptual sensitivity to it, and the difficulty of accurately describing it.

Multi-Concept Customization of Text-to-Image Diffusion [PDF]
Computer Vision and Pattern Recognition, 2022 While generative models produce high-quality images of concepts learned from a large-scale database, a user often wishes to synthesize instantiations of their own concepts (for example, their family, pets, or items).

Intercomparison of In Situ Sensors for Ground-Based Land Surface Temperature Measurements
Sensors, 2020 Land surface temperature (LST) is a key variable in the determination of land surface energy exchange processes from local to global scales. Accurate ground measurements of LST are necessary for a number of applications including validation of satellite ...

Artificial intelligence-based locoregional markers of brain peritumoral microenvironment
Scientific Reports, 2023 In malignant primary brain tumors, cancer cells infiltrate into the peritumoral brain structures which results in inevitable recurrence. Quantitative assessment of infiltrative heterogeneity in the peritumoral region, the area where biopsy or resection ...
