The Surprising Effectiveness of Diffusion Models for Optical Flow and Monocular Depth Estimation [PDF]
Neural Information Processing Systems, 2023 Denoising diffusion probabilistic models have transformed image generation with their impressive fidelity and diversity. We show that they also excel in estimating optical flow and monocular depth, surprisingly, without task-specific architectures and ...

Recent developments for the optical model of nuclei [PDF]
Progress in Particle and Nuclear Physics, 2018 A brief overview of various approaches to the optical-model description of nuclei is presented. A survey of some of the formal aspects is given which links the Feshbach formulation for either the hole or particle Green's function to the time-ordered ...

PWC-Net: CNNs for Optical Flow Using Pyramid, Warping, and Cost Volume [PDF]
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2017 We present a compact but effective CNN model for optical flow, called PWC-Net. PWC-Net has been designed according to simple and well-established principles: pyramidal processing, warping, and the use of a cost volume. Cast in a learnable feature pyramid,

Optical activity induced by curvature in a gravitational pp-wave background [PDF]
, 2002 We study optical activity induced by curvature. The optical activity model we present has two phenomenological gyration parameters, within which we analyze three model cases, namely, an exactly integrable model, the Landau-Lifshitz model and the Fedorov ...
