Information technology — JPEG 2000 image coding system — Part 9: Interactivity tools, APIs and protocols

This Document defines, in an extensible manner, syntaxes and methods for the remote interrogation and optional modification of JPEG 2000 codestreams and files in accordance with their definition in Rec. ITU-T T.800 | ISO/IEC 15444-1 and other members of the Rec. ITU-T T.8xx | ISO/IEC 15444-x family of Recommendations | Standards. In this document, the defined syntaxes and methods are referred to as the JPEG 2000 Interactive Protocol, "JPIP", and interactive applications using JPIP are referred to as "JPIP systems." JPIP specifies a protocol consisting of a structured series of interactions between a client and a server by means of which image file metadata, structure and partial or whole image codestreams can be exchanged in a manner that avoids or minimises the communication of information not required by client. This document includes definitions of the semantics and values to be exchanged, and suggests how these can be passed using a variety of existing network transports. With JPIP, the following tasks can be accomplished in varying, compatible ways: – the exchange of capabilities; – the negotiation of capabilities to use in a session; – the request and transfer of the following elements from a variety of containers, such as JPEG 2000 files, JPEG 2000 codestreams and other container files: • selective data segments; • selective and defined structures; • parts of an image or its related metadata.

Information technology — JPEG XS low-latency lightweight image coding system — Part 4: Conformance testing

This document specifies the framework, concepts, methodology for testing, and criteria to be achieved to claim conformance to multiple parts of the ISO/IEC 21122 series. It lists the conformance testing procedures. This document specifies: — Conformance testing procedures for decoders implementing ISO/IEC 21122-1. — Tests to check which conformance point an ISO/IEC 21122-1 decoder conforms to, that is, whether a decoder satisfies the error bounds required for strict or relaxed conformance. — Conformance testing procedures for decoders implementing ISO/IEC 21122-3. — Tests to check codestreams for conformance to ISO/IEC 21122-1. As such, it provides means to test whether encoder implementations generate syntactically correct codestreams, and whether codestreams generated by such implementations follow the requirements of a particular profile, level and sublevel, and the buffer model implied by them. — Tests to check files for conformance to ISO/IEC 21122-3. — Conformance testing procedures that allow testing whether codestreams conform to any of the profiles specified in ISO/IEC 21122-2. — Conformance testing procedures that allow testing whether codestreams conform to the buffer model specified in ISO/IEC 21122-2 as part of a profile, level and sublevel. — Codestreams, decoded images, and error metrics to be used within the decoder testing procedures. — A buffer model test. — Abstract test suites. NOTE: This document does not specify: — Testing the reconstruction of a full resolution image from a subsampled image format. In particular, upsampling from 4:2:2 or 4:2:0 to 4:4:4 sampling is a non-normative extension and as such its testing is beyond the scope of this document. — Testing the conversion of the sample values reconstructed by an ISO/IEC 21122-3 decoder to the target colour space by means of the colour specification box of ISO/IEC 21122-3. — Testing of the composition of background and foreground for images reconstructed from ISO/IEC 21122-3 files or codestreams that contain auxiliary channels carrying opacity information. — Testing of the interpolation of a colour filter array image to a full scale colour image; this process is not normatively defined and beyond the scope of this document. — Acceptance testing: the process of determining whether an implementation satisfies acceptance criteria and enables the user to determine whether or not to accept the implementation. This includes the planning and execution of several kinds of tests (e.g. functionality, quality, and speed performance testing) that demonstrate that the implementation satisfies the user requirements. — Performance testing: measures the performance characteristics of an implementation under test (IUT) such as its throughput, responsiveness, etc. under various conditions. — Robustness testing: the process of determining how well an implementation is able to conceal problems from attempting to reconstruct an image from an ill-formed codestream.

Information technology — JPEG XS low-latency lightweight image coding system — Part 1: Core coding system

This document defines the syntax and an accompanying decompression process that is capable to represent continuous-tone grey-scale, or continuous-tone colour digital images without visual loss at moderate compression rates. Typical compression rates are between 2:1 and 6:1 but can also be higher depending on the nature of the image. In particular, the syntax and the decoding process specified in this document allow lightweight encoder and decoder implementations that limit the end-to-end latency to a fraction of the frame size. However, the definition of transmission channel buffer models necessary to ensure such latency is beyond the scope of this document. This document: — specifies decoding processes for converting compressed image data to reconstructed image data; — specifies a codestream syntax containing information for interpreting the compressed image data; — provides guidance on encoding processes for converting source image data to compressed image data.

Information technology — JPEG 2000 image coding system — Part 1: Core coding system

This Recommendation | International Standard defines a set of lossless (bit-preserving) and lossy compression methods for coding bi-level, continuous-tone grey-scale, palletized colour, or continuous-tone colour digital still images. This Recommendation | International Standard: ? specifies decoding processes for converting compressed image data to reconstructed image data; ? specifies a codestream syntax containing information for interpreting the compressed image data; ? specifies a file format; ? provides guidance on encoding processes for converting source image data to compressed image data; ? provides guidance on how to implement these processes in practice. NOTE ? As this specification was first published as common text only after ISO/IEC JTC1 had approved the first edition in 2000, edition numbers in the ITU and ISO/IEC versions are offset by one. This is the third edition of ITU-T T.800 and the fourth edition of ISO/IEC 15444-1.

Information technology — JPEG 2000 image coding system — Part 15: High-Throughput JPEG 2000

This Recommendation | International Standard specifies an alternate block-coding algorithm that can be used in place of the block-coding algorithm specified in Rec. ITU-T T.800 | ISO/IEC 15444-1. This alternate block-coding algorithm offers a significant increase in throughput at the expense of slightly reduced coding efficiency, while a) allowing mathematically lossless transcoding to and from codestreams that use the block-coding algorithm specified in Rec. ITU‑T T.800 | ISO/IEC 15444-1, and b) preserving codestream syntax and features specified in Rec. ITU-T T.800 | ISO/IEC 15444-1. Recommendation ITU-T T.814 (2019) is a common text with ISO/IEC 15444-15:2019, both in their first edition.

Information technology — Lossy/lossless coding of bi-level images

This Recommendation | International Standard defines methods for coding bi-level images and sets of images (documents consisting of multiple pages). It is particularly suitable for bi-level images consisting of text and dithered (halftone) data. The methods defined permit lossless (bit-preserving) coding, lossy coding, and progressive coding. In progressive coding, the first image is lossy; subsequent images may be lossy or lossless. This Recommendation | International Standard also defines file formats to enclose the coded bi-level image data.

Space - Earth observation - Image processing levels
SIST EN 17030:2018

This European Standard specifies the definition of the different processing steps (levels) of images coming from Earth observation systems observing the surface of the Earth regarding the different sensor sources of the origin data.
It applies at least to image products generated from the following types of sensors:
-   electro-optical (including infrared and hyper-spectral);
-   SAR (Synthetic Aperture Radar).
The standard allows to identify the information depth and the used auxiliary data/information. Furthermore it allows the comprehension of image data from different sources and gives hints about the information compatibility.

ISO/IEC TR 29170-1:2017(Main)
Information technology — Advanced image coding and evaluation — Part 1: Guidelines for image coding system evaluation

ISO/IEC TR 29170-1:2017 recommends best practices for coding system evaluation of images and image sequences. ISO/IEC TR 29170-1:2017 defines a common vocabulary of terms for coding system evaluation and divides evaluation methods into three broad categories: a) subjective assessment; b) objective assessment; c) computational assessment. In addition to these broad assessment categories, this document discusses special care that is given for coding unusual imagery, e.g. high dynamic range or high colour depth. A fourth assessment category, hardware complexity, is often important for real-time or computationally complex applications; however, it is outside the scope of this document.
