What is ISO 15882: 2017?

ISO 15882: 2017, also known as Electronic imaging - Coding of still pictures in JPEG 2000 format - Part 1: Core coding system, is a technical standard developed by the International Organization for Standardization (ISO) that governs the coding of still pictures in the JPEG 2000 format. This standard was first published in 2003 and has since been updated to its current version in 2017.

Core Features of ISO 15882: 2017

The core coding system defined by ISO 15882: 2017 provides several key features for efficient and high-quality image compression. One of the main features is the use of wavelet-based compression techniques, which allow for better preservation of image details compared to traditional methods such as the original JPEG format. This makes JPEG 2000 particularly suitable for applications where image quality is crucial, such as medical imaging or archival purposes.

In addition to improved image quality, ISO 15882: 2017 also supports various advanced functionalities, including region of interest coding, selective quality coding, and scalable image coding. These features provide flexibility in image manipulation and transmission, allowing users to prioritize specific regions or levels of detail within an image.

Benefits and Applications

The adoption of ISO 15882: 2017 brings numerous benefits to both professional and everyday users. Firstly, the superior compression capabilities of JPEG 2000 enable more efficient storage and transmission of large image datasets. This is especially important in fields where high-resolution images, such as satellite imagery or digital cinema, are frequently handled.

Moreover, the advanced functionalities offered by ISO 15882: 2017 make it an ideal choice for applications requiring interactive viewing and manipulation of images. For instance, the region of interest coding feature allows users to transmit and display specific areas of an image with higher quality, which is useful in telemedicine or remote sensing applications.

Conclusion

ISO 15882: 2017 is a technical standard that defines the core coding system for still pictures in the JPEG 2000 format. Its adoption brings improved image quality, efficient compression, and advanced functionalities for various applications. As technology continues to evolve, standards like ISO 15882: 2017 play a vital role in ensuring interoperability and compatibility across different systems and platforms.
