Abstract

Quality is a fundamental concept closely linked to measuring performance in systems, products and services. Any compression and representation technique in audiovisual signals needs metrics of quality, not only in their design stage but also in demonstrating their superior performance when compared to state of the art. Some believe that the main reason for the failure of previous waves of 3D was the lack of a minimum quality requirement in 3D. It is therefore important to consider mechanisms of 3D vision in humans, and their underlying perceptual models, in conjunction with the type of distortions that today and tomorrow 3D video processing systems produce. In this chapter, we will examine some parts of this complex puzzle, by mainly focusing on an important issue, namely, how to measurement 3D visual quality, as an essential factor in the success of 3D technologies, products and services.

3D scanning

3D scanner is the process of analyzing a real-world object or environment to collect three dimensional data of its shape and possibly its appearance (e.g. color). The collected data can then be used to construct digital 3D models. A 3D scanner can be based on many different technologies, each with its own limitations, advantages and costs. Many limitations in the kind of objects that can be digitised are still present. For example, optical technology may encounter many difficulties with dark, shiny, reflective or transparent objects.

Quality (business)

In business, engineering, and manufacturing, quality – or high quality – has a pragmatic interpretation as the non-inferiority or superiority of something (goods or services); it is also defined as being suitable for the intended purpose (fitness for purpose) while satisfying customer expectations. Quality is a perceptual, conditional, and somewhat subjective attribute and may be understood differently by different people. Consumers may focus on the specification quality of a product/service, or how it compares to competitors in the marketplace.

Video quality

Video quality is a characteristic of a video passed through a video transmission or processing system that describes perceived video degradation (typically, compared to the original video). Video processing systems may introduce some amount of distortion or artifacts in the video signal that negatively impacts the user's perception of a system. For many stakeholders in video production and distribution, assurance of video quality is an important task. Video quality evaluation is performed to describe the quality of a set of video sequences under study.
