EvRepSL: Event-Stream Representation via Self-Supervised Learning for Event-Based Vision

1 code implementation10 Dec 2024 Qiang Qu, Xiaoming Chen, Yuk Ying Chung, Yiran Shen

However, most of the state-of-the-art event-stream representations are manually designed and the quality of these representations cannot be guaranteed due to the noisy nature of event-streams.

Texture-enhanced Light Field Super-resolution with Spatio-Angular Decomposition Kernels

no code implementations7 Nov 2021 Zexi Hu, Xiaoming Chen, Henry Wing Fung Yeung, Yuk Ying Chung, Zhibo Chen

Despite the recent progress in light field super-resolution (LFSR) achieved by convolutional neural networks, the correlation information of light field (LF) images has not been sufficiently studied and exploited due to the complexity of 4D LF data.

Fast Light Field Reconstruction With Deep Coarse-To-Fine Modeling of Spatial-Angular Clues

1 code implementation ECCV 2018 Henry Wing Fung Yeung, Junhui Hou, Jie Chen, Yuk Ying Chung, Xiaoming Chen

Specifically, our end-to-end model first synthesizes a set of intermediate novel sub-aperture images (SAIs) by exploring the coarse characteristics of the sparsely-sampled LF input with spatial-angular alternating convolutions.
