Edge-Focused Super-Resolution for Omnidirectional Images with Spherical Geometric Augmentation

CVPR 2026

Omnidirectional image super-resolution (ODISR) remains challenging due to extreme magnification factors (e.g., 8x, 16x) and projection-specific distortions, which degrade edge integrity and limit model performance. This paper proposes an edge-focused framework combined with spherical geometric augme

Microexpression to Macroexpression: Facial Expression Magnification by Single Input

ICRA 2024poster

Microexpressions are expressions that people inadvertently express, and therefore often represent a person’s true emotion. However, because it has a low intensity and a short duration, it is hard to be recognized correctly. In this paper, we propose a deep learning magnification method to generate m…

Asynchronous Decentralized SGD with Quantized and Local Updates

NeurIPS 2021poster

Decentralized optimization is emerging as a viable alternative for scalable distributed machine learning, but also introduces new challenges in terms of synchronization costs. To this end, several communication-reduction techniques, such as non-blocking communication, quantization, and local step…
