Space-Time Video Regularity and Visual Fidelity: Compression, Resolution and Frame Rate Adaptation
Dae Yeol Lee, Hyunsuk Ko, Jongho Kim +1
In order to be able to deliver today's voluminous amount of video contents through limited bandwidth channels in a perceptually optimal way, it is important to consider perceptual…
A Subjective and Objective Study of Space-Time Subsampled Video Quality
Dae Yeol Lee, Somdyuti Paul, Christos G. Bampis +5
Video dimensions are continuously increasing to provide more realistic and immersive experiences to global streaming and social media viewers. However, increments in video paramete…
On the Space-Time Statistics of Motion Pictures
Dae Yeol Lee, Hyunsuk Ko, Jongho Kim +1
It is well-known that natural images possess statistical regularities that can be captured by bandpass decomposition and divisive normalization processes that approximate early neu…
Quality Prediction on Deep Generative Images
Hyunsuk Ko, Dae Yeol Lee, Seunghyun Cho +1
In recent years, deep neural networks have been utilized in a wide variety of applications including image generation. In particular, generative adversarial networks (GANs) are abl…
A ParaBoost Stereoscopic Image Quality Assessment (PBSIQA) System
Hyunsuk Ko, Rui Song, C. -C. Jay Kuo
The problem of stereoscopic image quality assessment, which finds applications in 3D visual content delivery such as 3DTV, is investigated in this work. Specifically, we propose a…
Robust Uncalibrated Stereo Rectification with Constrained Geometric Distortions (USR-CGD)
Hyunsuk Ko, Han Suk Shim, Ouk Choi +1
A novel algorithm for uncalibrated stereo image-pair rectification under the constraint of geometric distortion, called USR-CGD, is presented in this work. Although it is straightf…
MCL-3D: a database for stereoscopic image quality assessment using 2D-image-plus-depth source
Rui Song, Hyunsuk Ko, C. C. Jay Kuo
A new stereoscopic image quality assessment database rendered using the 2D-image-plus-depth source, called MCL-3D, is described and the performance benchmarking of several known 2D…
