Optimization of phase-only holograms calculated with scaled diffraction calculation through deep neural networks
Yoshiyuki Ishii, Tomoyoshi Shimobaba, David Blinder +4
Computer-generated holograms (CGHs) are used in holographic three-dimensional (3D) displays and holographic projections. The quality of the reconstructed images using phase-only CG…
Comprehensive Performance Analysis of Objective Quality Metrics for Digital Holography
Ayyoub Ahar, Tobias Birnbaum, Maksymilian Chlipala +5
Objective quality assessment of digital holograms has proven to be a challenging task. While prediction of perceptual quality of the recorded 3D content from the holographic wavefi…
QUALINET White Paper on Definitions of Immersive Media Experience (IMEx)
Andrew Perkis, Christian Timmerer, Sabina Baraković +41
With the coming of age of virtual/augmented reality and interactive media, numerous definitions, frameworks, and models of immersion have emerged across different fields ranging fr…
Suitability Analysis of Holographic vs Light Field and 2D Displays for Subjective Quality Assessment of Fourier Holograms
Ayyoub Ahar, Maksymilian Chlipala, Tobias Birnbaum +5
Visual quality assessment of digital holograms is facing many challenges. Main difficulties are related to the limited spatial resolution and angular field of view of holographic d…
From Adaptive Kernel Density Estimation to Sparse Mixture Models
Colas Schretter, Jianyong Sun, Peter Schelkens
We introduce a balloon estimator in a generalized expectation-maximization method for estimating all parameters of a Gaussian mixture model given one data sample per mixture compon…
Proceedings of the second "international Traveling Workshop on Interactions between Sparse models and Technology" (iTWIST'14)
L. Jacques, C. De Vleeschouwer, Y. Boursier +64
The implicit objective of the biennial "international - Traveling Workshop on Interactions between Sparse models and Technology" (iTWIST) is to foster collaboration between interna…
The near shift-invariance of the dual-tree complex wavelet transform revisited
Adriaan Barri, Ann Dooms, Peter Schelkens
The dual-tree complex wavelet transform (DTCWT) is an enhancement of the conventional discrete wavelet transform (DWT) due to a higher degree of shift-invariance and a greater dire…
