TL;DR: An Attentive Fractal Network is proposed to effectively solve the problem of moiré pattern removal compared to existing state-of-the-art methods, and the effectiveness of its each component is proved.
S3IM: Stochastic Structural SIMilarity and Its Unreasonable Effectiveness for Neural Fields
TL;DR: To the best of the knowledge, this work is the first to design a nonlocal multiplex training paradigm for NeRF and relevant neural field methods via a novel Stochastic Structural SIMilarity (S3IM) loss that processes multiple data points as a whole set instead of process multiple inputs independently.
Joint neural phase retrieval and compression for energy- and computation-efficient holography on the edge
TL;DR: This work proposes the first framework that jointly generates and compresses high-quality phase-only holograms, and is robust to transmission and decoding errors, and approach high image fidelity for as low as 2 bits-per-pixel, and further reduced average bit-rates and decoding time for holographic videos.
