What is BS EN ISO 33023:2019?

BS EN ISO 33023:2019 is a technical standard that provides guidelines and requirements for the application of visual perception to digital images or videos. It focuses on defining metrics and procedures for assessing the quality of images and videos based on human visual perception. This standard plays a crucial role in various industries, such as broadcasting, media, and telecommunications, where the quality of images and videos is essential. In this article, we will dive into the details of BS EN ISO 33023:2019 and explore its significance in the digital imaging field.

Scope and Key Principles

The scope of BS EN ISO 33023:2019 encompasses the measurement and assessment of the perceived image or video quality using subjective or objective methods. It provides guidelines for conducting experiments and collecting data from human observers, as well as defining computational models for predicting the perceived quality. The standard also covers processes for analyzing the collected data and drawing appropriate conclusions related to image or video quality.

One of the key principles underlying BS EN ISO 33023:2019 is the importance of considering human visual perception in image and video quality assessment. The standard acknowledges that human observers are the ultimate judges of quality, and their perceptual experiences should be taken into account when evaluating the performance of imaging systems or algorithms.

Metrics and Procedures for Quality Assessment

BS EN ISO 33023:2019 defines a range of metrics and procedures for image and video quality assessment. These metrics include both subjective and objective measures. Subjective measures involve human observers rating the quality of images or videos based on their own perception. Objective measures, on the other hand, utilize computational algorithms to predict the perceived quality without human involvement.

The standard provides detailed guidelines for designing experiments, selecting appropriate testing conditions, and evaluating the impact of various factors on perceived quality. It also addresses issues related to cross-media comparison, where the quality of different types of media, such as images and videos, needs to be assessed consistently.

Significance in the Digital Imaging Field

BS EN ISO 33023:2019 is of great significance in the digital imaging field. It allows manufacturers, service providers, and researchers to objectively assess the quality of their imaging systems or algorithms. By following the guidelines provided in this standard, they can ensure that the end-users have a satisfactory visual experience when viewing images or videos.

Moreover, adherence to BS EN ISO 33023:2019 facilitates fair competition among businesses in the industry. By using standardized metrics and procedures, companies can compare and evaluate the performance of different imaging technologies more accurately, which leads to better product development and ultimately benefits the end-users.

In conclusion, BS EN ISO 33023:2019 sets the standards for assessing image and video quality based on human visual perception. It establishes guidelines, metrics, and procedures that contribute to the improvement of digital imaging technologies across various industries. By conforming to this standard, companies can ensure that their imaging systems or algorithms meet the expectations of end-users.
