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…
