Dynamic Neural Radiance Fields for Monocular 4D Facial Avatar Reconstruction [PDF]

Computer Vision and Pattern Recognition, 2020
We present dynamic neural radiance fields for modeling the appearance and dynamics of a human face1. Digitally modeling and reconstructing a talking human is a key building-block for a variety of applications. Especially, for telepresence applications in

Effect of light pollution on self-reported sleep quality and its components: Comparative assessment among healthy adult populations in a rural and an Urban area of West Bengal, India

Indian Journal of Public Health, 2020
Background: Light pollution is inappropriate or excessive use of artificial light. Nighttime sky radiance is an effective measure to study its effects on individual sleep quality. Objectives: The study is aimed to measure the effect of light pollution on

Stefan-Boltzmann law for massive photons

, 2016
This paper generalizes the Stefan-Boltzmann law to include massive photons. A crucial ingredient to obtain the correct formula for the radiance is to realize that a massive photon does not travel at the speed of (massless) light.

iNeRF: Inverting Neural Radiance Fields for Pose Estimation [PDF]

IEEE/RJS International Conference on Intelligent RObots and Systems, 2020
We present iNeRF, a framework that performs mesh-free pose estimation by "inverting" a Neural Radiance Field (NeRF). NeRFs have been shown to be remarkably effective for the task of view synthesis — synthesizing photorealistic novel views of real-world ...

Utility of Computed Tomography Surveillance of Asymptomatic Infection in Children and Young Adults Before Allogeneic Hematopoietic Stem Cell Transplant

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Asymptomatic infection poses a significant risk for children undergoing hematopoietic stem cell transplantation (HSCT). Pre‐transplant surveillance computed tomography (CT) is commonly used to identify occult infection, though its diagnostic yield remains uncertain.
