Standardized toolchain and model development for video quality assessment — The mission of the Joint Effort Group in VQEG

Abstract

Since 1997, the Video Quality Experts Group (VQEG) has been active in the field of subjective and objective video quality assessment. The group has validated competitive quality metrics throughout several projects. Each of these projects requires mandatory actions such as creating a testplan and obtaining databases consisting of degraded video sequences with corresponding subjective quality ratings. Recently, VQEG started a new open initiative, the Joint Effort Group (JEG), for encouraging joint collaboration on all mandatory actions needed to validate video quality metrics. Within the JEG, effort is made to advance the field of both subjective and objective video quality measurement by providing proper software tools and subjective databases to the community. One of the subprojects of the JEG is the joint development of a hybrid H.264/AVC objective quality metric. In this paper, we introduce the JEG and provide an overview of the different ongoing activities within this newly started group.

No-Reference Bitstream-Based Visual Quality Impairment Detection for High Definition H.264/AVC Encoded Video Sequences

“…Video quality metrics can also use a combination of pixel, bitstream and network information for calculating perceived quality. Such objective metrics are also known as hybrid metrics and are currently being evaluated by the Video Quality Experts Group (VQEG) [23], [24]. Classification of video quality metrics based on the amount of information which is used from the reference sequence or based on the processing level for extracting information in order to model perceived quality.…”

Error Resilient for Multiview Video Transmissions with GOP Analysis

“…The Sirannon network simulator is a modular multimedia streamer which supports a wide variety of video formats and streaming protocols for use both in real time video streaming and offline simulation [21]. In this simulation, the offline mode is used.…”

The history of video quality model validation

“…Reports for each VQEG validation effort are available at [5]. More recently, VQEG efforts have also included collaborative research efforts and new subjective methods that are outside of the scope of this paper (e.g., [6]- [8]). …”
