Abstract:

This paper presents the color-dependent method of removing inter-view redundancy from multiview video. The pruning of input views decides which fragments of views are redundant, i.e., do not provide new information about the three-dimensional scene, as these fragments were already visible from different views. The proposed modification of the pruning uses both color and depth and utilizes the adaptive pruning threshold which increases the robustness against the noisy input. As performed experiments have shown, the proposal provides significant improvement in the quality of encoded multiview vi

Abstract:

In this paper, we present a new objective quality metric designed for immersive video applications—IV-SSIM. The proposed IV-SSIM metric is an evolution of our previous work—IV-PSNR (immersive video peak signal-to-noise ratio)—which became a commonly used metric in research and ISO/IEC MPEG standardization activities on immersive video. IV-SSIM combines the advantages of IV-PSNR and metrics based on the structural similarity of images, being able to properly mimic the subjective quality perception of immersive video with its characteristic distortions induced by the reprojection of pixels betwe

Abstract:

In this paper, the authors describe two methods designed for reducing the spatiotemporal redundancy of the video within the MPEG Immersive video (MIV) encoder: patch occupation modification and cluster splitting. These methods allow optimizing two important parameters of the immersive video: bitrate and pixelrate. The patch occupation modification method significantly decreases the number of active pixels within texture and depth video produced by the MIV encoder. Cluster splitting decreases the total area needed for storing the texture and depth information from multiple input views, decreasi

Abstract:

Immersive video enables interactive natural consumption of visual content by empowering a user to navigate through six degrees of freedom, with motion parallax and wide-angle rotation. Supporting immersive experiences requires content captured by multiple cameras and efficient video coding to meet bandwidth and decoder complexity constraints, while delivering high quality video to end users. The Moving Picture Experts Group (MPEG) is developing an immersive video (MIV) standard to data access and delivery of such content. One of MIV operating modes is an objectbased immersive video coding whic

This paper presents the modified HEVC Screen Content Coding (SCC) that was adapted to be more efficient as an internal video coding of the MPEG Immersive Video (MIV) codec.

First, we analyze using the quarter-pel accuracy in the intra block copy technique to provide a more effective search of the best candidate block to be copied in the encoding process.

Recently, with the increasing demand for virtual reality (VR), experiencing immersive contents with VR has become easier. However, a tremendous amount of calculation and bandwidth is required when processing 360 videos.

Therefore, this paper proposes an efficient method of streaming high-quality 360 videos.

A 360° video offers a more immersive experience, gaining increasing popularity among users. However, enhancing the transmission efficiency of 360° videos under limited bandwidth conditions remains a significant challenge.

Based on the segmentation of these three distinct video areas, a novel non-uniform coding transmission method for 360° videos is presented, along with mathematical modeling to define the optimization problem.

Video compression plays a pivotal role in managing the storage and transmission of multimedia content, especially in bandwidth-constrained environments. Nowadays, volumetric video has emerged as an attractive multimedia application, which provides highly immersive watching experiences. How- ever, streaming the volumetric video demands prohibitively high bandwidth. Thus, effectively compressing its underlying point cloud frames is essential to deploying the volumetric videos. The existing compression techniques are either 3D-based or 2D-based, but they still have drawbacks when being deployed i

Immersive video streaming technologies improve Virtual Reality (VR) user experience by providing users more intuitive ways to move in simulated worlds, e.g., with 6 Degree-of-Freedom (6DoF) interaction mode. A naive method to achieve 6DoF is deploying cameras at numerous different positions and orientations that may be required based on users’ movement, which unfortunately is expensive, tedious, and inefficient. A better solution for realizing 6DoF interactions is to synthesize target views on-the-fly from a limited number of source views. While such view synthesis is enabled by the recent Tes

Abstract:

Abstract 8K video parameters were designed to provide an immersive experience; meanwhile, special considerations are necessary to assess the entire screen subjectively. This paper studies the video bit-rate required for 8K 119.88-Hz (120-Hz) and 59.94-Hz (60-Hz) the high efficiency video coding (HEVC)/H.265 temporal scalable coding based on subjective evaluation experiments. To investigate the appropriate bit-rate for both 8K 120- and 60-Hz videos for broadcasting purposes, we compress 8K 120-Hz test sequences using software that emulates our real-time HEVC encoder and conduct two types of exp

Abstract:

Three-sixty video-ethnography is a growing field of research, offering novel insights into the complex interactions between individuals and their environments. Despite its potential, the application of 360-degree video in qualitative research remains underexplored. The study presented here aims to bridge this gap, by discussing an approach to data collection and visual analysis, grounded in a multimodal epistemological framework for in-depth qualitative exploration of place-based interactions. Specifically, the paper investigates the integration of 360-degree videos and Virtual Reality Head-Mo

Abstract:

The increasing popularity of virtual, augmented, and mixed reality (VR/AR/MR) applications is driving the media industry to explore the creation and delivery of new immersive experiences. One of the trends is volumetric video, which allows users to explore content unconstrained by the traditional two-dimensional window of director’s view.The ISO/IEC joint technical committee 1 subcommittee 29, better known as the Moving Pictures Experts Group (MPEG), has recently finalized a group of standards, under the umbrella of Visual Volumetric Video-based Coding (V3C). These standards aim to efficiently

Abstract:

ABSTRACTIn this paper, we propose a machine learning‐driven model to optimize panoramic video transmission for multiple users in virtual reality environments. The model predicts users' future field of view (FOV) using historical head orientation data and video saliency information, enabling targeted video delivery based on individual perspectives. By segmenting panoramic videos into tiles and applying a pyramid coding scheme, we adaptively transmit high‐quality content within users' FOVs while utilizing lower‐quality transmissions for peripheral regions. This approach effectively reduces bandw

Abstract This article presents an overview of the recent standardization activities for point cloud compression (PCC). A point cloud is a 3D data representation used in diverse applications associated with immersive media including virtual/augmented reality, immersive telepresence, autonomous driving and cultural heritage archival. The international standard body for media compression, also known as the Motion Picture Experts Group (MPEG), is planning to release in 2020 two PCC standard specifications: video-based PCC (V-CC) and geometry-based PCC (G-PCC). V-PCC and G-PCC will be part of the I

AbstractThis study examines the embodied ways in which learners monitor their cognition while learning about exponential functions in an immersive virtual reality (VR) based game, Pandemic by Prisms of Reality. Traditionally, metacognitive monitoring has been assessed through behavioural traces and verbalised instances. When learning in VR, learners are fully immersed in the learning environment, actively manipulating it based on affordances designed to support learning, offering insights into the relationship between physical interaction and metacognition.

Abstract:

Point clouds offer realistic three-dimensional (3-D) representations of objects and scenes at the expense of large data volumes. To represent such data compactly in real-world applications, Video-based Point Cloud Compression (V-PCC) converts their texture into two-dimensional (2-D) attributes and occupancy maps before applying lossy video compression. Unfortunately, the coding artifacts introduced in the decoded attribute maps eventually degrade the quality of the reconstructed point cloud, thereby influencing its immersive experience. This paper proposes a deep learning-based attribute map e
