Real-Time AI-Driven Avatar Generation for Sign Language in HTTP Adaptive Streaming

Real-Time AI-Driven Avatar Generation for Sign Language in HTTP Adaptive Streaming

The 3rd ACM SIGCOMM Workshop on Emerging Multimedia Systems (ACM EMS 2025)

https://conferences.sigcomm.org/sigcomm/2025/workshop/ems/

Abstract: As digital media consumption over the Internet surges globally, ensuring accessibility for all users becomes paramount. For people with hearing impairments, this means providing inclusion beyond classic captioning, which does not convey the full emotional and contextual depth of spoken content. This work addresses this accessibility gap by exploring the use of AI-generated avatars capable of translating speech into sign language in real-time. After defining the multifaceted challenges in this domain, we propose a novel AI-driven task partition to animate avatars for accurate and expressive sign language interpretations in live streaming.

Abstract: Image complexity (IC) plays a critical role in both cognitive science and multimedia computing, influencing visual aesthetics, emotional responses, and tasks such as image classification and enhancement. However, defining and quantifying IC remains challenging due to its multifaceted nature, which encompasses both objective attributes (e.g., detail, structure) and subjective human perception. While traditional methods rely on entropy-based or multidimensional approaches, and recent advances employ machine learning and shallow neural networks, these techniques often fail to fully capture the subjective aspects of IC. Inspired by the fact that the human visual system inherently perceives implicit motion in static images, we propose a novel approach to address this gap by explicitly incorporating hidden motion into IC assessment. We introduce the motion-inspired image complexity assessment metric (MICM) as a new framework for this purpose. MICM introduces a dual-branch architecture: One branch extracts spatial features from static images, while the other generates short video sequences to analyze latent motion dynamics. To ensure meaningful motion representation, we design a hierarchical loss function that aligns video features with text prompts derived from image-to-text models, refining motion semantics at both local (i.e., frame and word) and global levels. Experiments on three public image complexity assessment (ICA) databases demonstrate that our approach, MICM, significantly outperforms state-of-the-art methods, validating its effectiveness. The code will be publicly available upon acceptance of the paper.

PGDA Visits ITEC/GSE

On Friday, 13 June 2025, The Pioneers of Game Development Austria, the game development association focused on supporting, showcasing, and accelerating Austrian games, developers, and business, visited ITEC.

 

In an event organised by Dr Felix Schniz, Martin Filipp (Mi’pu’mi Games and PGDA representative) brought a delegation of industry representatives to campus, including Michael Benda (Zeppelin Studio), Raffael Moser (reignite games), and Manuel Bonell (Immerea). They held presentations on the status quo of the Austrian games industry and entertained a developer café in the afternoon, where students could sign up for discussion slots to ask questions about how to get into the industry and how to start your own gaming studio.

 

The event was visited by over 40 visitors, most of them students of the master’s programme Game Studies and Engineering.

Journal paper accepted – Elsevier SPIC: 360-Degree Video Super Resolution and Quality Enhancement Challenge: Methods and Results

Journal: Signal Processing: Image Communication

Abstract: Omnidirectional (360-degree) video is rapidly gaining popularity due to advancements in immersive technologies like virtual reality (VR) and extended reality (XR). However, real-time streaming of such videos, particularly in live mobile scenarios such as unmanned aerial vehicles (UAVs), is hindered by limited bandwidth and strict latency constraints. While traditional methods such as compression and adaptive resolution are helpful, they often compromise video quality and introduce artifacts that diminish the viewer’s experience. Additionally, the unique spherical geometry of 360-degree video, with its wide field of view, presents challenges not encountered in traditional 2D video. To address these challenges, we initiated the 360-degree Video Super Resolution and Quality Enhancement challenge. This competition encourages participants to develop efficient machine learning (ML)-powered solutions to enhance the quality of low-bitrate compressed 360-degree videos, under two tracks focusing on 2× and 4× super-resolution (SR). In this paper, we outline the challenge framework, detailing the two competition tracks and highlighting the SR solutions proposed by the top-performing models. We assess these models within a unified framework, (i) considering quality enhancement, (ii) bitrate gain, and (iii) computational efficiency. Our findings show that lightweight single-frame models can effectively balance visual quality and runtime performance under constrained conditions, setting strong baselines for future research. These insights offer practical guidance for advancing real-time 360-degree video streaming, particularly in bandwidth-limited immersive applications.

EUVIP’25 Tutorial: From Subjective Ratings to Objective Metrics

EUVIP 2025
October 13-16, 2025

Malta

Link

Tutorial speakers:

  • Wei Zhou (Cardiff University)
  • Hadi Amirpour (University of Klagenfurt)

Tutorial description:

As multimedia services like video streaming, video conferencing, virtual reality (VR), and online gaming continue to evolve, ensuring high perceptual visual quality is crucial for enhancing user experience and maintaining competitiveness. However, multimedia content inevitably undergoes various distortions during acquisition, compression, transmission, and storage, leading to quality degradation. Therefore, perceptual visual quality assessment, which evaluates multimedia quality from a human perception perspective, plays a vital role in optimizing user experience in modern communication systems. This tutorial provides a comprehensive overview of perceptual visual quality assessment, covering both subjective methods, where human observers directly rate their experience, and objective methods, where computational models predict perceptual quality based on measurable factors such as bitrate, frame rate, and compression levels. The session also explores quality assessment metrics tailored to different types of multimedia content, including images, videos, VR, point clouds, meshes, and AI-generated media. Furthermore, we discuss challenges posed by diverse multimedia characteristics, complex distortion scenarios, and varying viewing conditions. By the end of this tutorial, attendees will gain a deep understanding of the principles, methodologies, and latest advancements in perceptual visual quality assessment for multimedia communication.

Multimodal Learning for Visual Intelligence: From Emerging Techniques to Real-World Applications

In recent years, the integration of vision with complementary modalities such as language, audio, and sensor signals has emerged as a key enabler for intelligent systems that operate in unstructured environments. The emergence of foundation models and cross-modal pretraining has brought a paradigm shift to the field, making it timely to revisit the core challenges and innovative techniques in multimodal visual understanding.

This Special Issue aims to collect cutting-edge research and engineering practices that advance the understanding and development of visual intelligence systems through multimodal learning. The focus is on the deep integration of visual information with complementary modalities such as text, audio, and sensor data, enabling more comprehensive perception and reasoning in real-world environments. We encourage contributions from both academia and industry that address current challenges and propose novel methodologies for multimodal visual understanding.

Topics of interest include, but are not limited to:

  • Multimodal data alignment and fusion strategies with a focus on visual-centric modalities
  • Foundation models for multimodal visual representation learning
  • Generation and reconstruction techniques in visually grounded multimodal scenarios
  • Spatiotemporal modeling and relational reasoning of visual-centric multimodal data
