Telecommunication-Telemedia-Assessment — who are we?

This GitHub organization is a team of researchers who are working on methods, tools, and solutions for the assessment of telecommunication and telemedia technology. Key aspect of our approach is to consider both the user and technical information (system parameters, signals) in the assessment of technology.

We are current or former members of two university chairs:

• Audiovisual Technology Group (AVT), Institute for Media Technology — TU Ilmenau, Germany
• Assessment of IP-based Applications (AIPA), Telekom Innovation Laboratories / TU Berlin, Germany

Collection of repositories

📹 Video Quality

Models

• AVQBits: The AVQBits model collection is a set of open-source extensions for the ITU-T P.1204.3 model operating in different modes.

• P.1204.3 and P.1203 Overview: An introduction to P.1203 and P.1204.3 models and their implementation.

• ITU-T P.1204.3 Reference Implementation: Open source reference implementation of ITU-T P.1204.3

• bitstream_mode3_videoparser: The video parser required for extracting the data for the P.1204.3 model.

• ITU-T P.1203 Repositories: Collection of repositories for ITU-T P.1203 standard for HTTP Adaptive Streaming quality measurement.

• Cencro: A center cropped variant of Netflix’s VMAF.: Cencro uses center croped videos to speedup full reference video quality calculation.

Databases

• AVT-VQDB-UHD-1: A Large Scale Video Quality Database for UHD-1: This is a repository with data related to 4K databases published at IEEE-ISM 2019.

• AVT-VQDB-UHD-1-HDR: The UHD-1/4K HDR database published at IEEE QoMEX 2024.

• AVT-VQDB-UHD-2-HDR: The UHD-2/8K HDR database published at IEEE QoMEX 2024.

Tools

• frankenstone toolbox: A toolbox to evaluate and unify models and features for user-generated video quality.

• avrateNG: avrateNG is a video, image, and general multimedia rating system, based on a simple web interface.

• SITI: A command-line-based tool for Windows to calculate spatial information (SI) and temporal information (TI) according to previous versions of ITU-T P.910 (note: deprecated in favor of VQEG/siti-tools)

🖼 Image Quality

• Image Compression Evaluation: An evaluation of different video codecs to compress still images, there is also a dataset included.
• Sophoappeal Project: Evaluation of image appeal (dataset, models and more).

👁️ Saliency Prediction

• GBVS360, BMS360, ProSal: Extending existing saliency prediction models from 2D to omnidirectional images.

👓 Virtual Reality

• AVT-ECoClass-VR: The AVT-ECoClass-VR database that is published at the IEEE QoMEX 2024 conference.

• AVTrack360: This repository contains AVTrack360, a tool for recording the 3 rotation angles Pitch/Yaw/Roll around the 3 Axes X/Y/Z while a user is watching an omnidirectional video via an HMD. It also contains a dataset of the head rotation data and Simulator Sickness Questionnaire (SSQ) results of 48 participants watching 20 30s long different omnidirectional videos using the HTC Vive. Tools for evaluating the SSQ and head rotation data are also given.

• Distance Differences Ives: This repository contains the Unity project of the paper with the title “Development and evaluation of a test setup to investigate distance differences in immersive virtual environments” published at QoMEX 2020

👥 CrowdSourcing

• AVrateVoyager: An online based image/video/audio quality testing framework.

• CrowdWatcher: This project is the open-source eye tracking platform. It enables researchers to measure visual attention and user engagement in a crowdsourcing context through traditional RGB webcams.
