CV-HoloSR: Hologram to hologram super-resolution through volume-upsampling three-dimensional scenes
Youchan No, Jaehong Lee, Daejun Choi +2
Existing hologram super-resolution (HSR) methods primarily focus on angle-of-view expansion. Adapting them for volumetric spatial up-sampling introduces severe quadratic depth dist…

A Large-Depth-Range Layer-Based Hologram Dataset for Machine Learning-Based 3D Computer-Generated Holography
Jaehong Lee, You Chan No, YoungWoo Kim +1
Machine learning-based computer-generated holography (ML-CGH) has advanced rapidly in recent years, yet progress is constrained by the limited availability of high-quality, large-s…

Fourier-Guided Attention Upsampling for Image Super-Resolution
Daejune Choi, Youchan No, Jinhyung Lee +1
We propose Frequency-Guided Attention (FGA), a lightweight upsampling module for single image super-resolution. Conventional upsamplers, such as Sub-Pixel Convolution, are efficien…
