信息技术.JPEG 2000图像编码系统.第4部分:一致性试验

[中文适用范围]： 本文件规定了声明符合ITU-T Rec. T.800 | ISO/IEC 15444-1或ITU-T Rec. T.814 | ISO/IEC 15444-15要求的测试框架、概念、方法和达标标准。它为具体测试套件（ATS）的规范以及符合性测试过程中需要遵循的程序提供了框架。本文件规定了使用ITU-T Rec. T.800 | ISO/IEC 15444-1和ITU-T Rec. T.814 | ISO/IEC 15444-15进行编码和解码的符合性测试程序；规定了与测试程序一起使用的代码流、解码图像和误差度量；规定了ATS；并提供了创建符合编码器测试指南。本文件不包括以下测试：验收测试：确定实现是否满足验收标准的过程，使用户能够决定是否接受该实现。这包括计划和执行多种类型的测试（例如功能测试、质量测试和速度性能测试），以证明实现满足用户要求。性能测试：衡量正在测试的实施（IUT）在各种条件下的性能特性，如吞吐量和响应性。鲁棒性测试：确定实现处理包含错误的数据的能力的过程。 [外文原描述]： This Recommendation | International Standard specifies the framework, concepts, methodology for testing, and criteria to be achieved to claim compliance to Rec. ITU-T T.800 | ISO/IEC 15444-1 or Rec. ITU-T T.814 | ISO/IEC 15444-15. It provides a framework for specifying abstract test suites (ATSs) and for defining the procedures to be followed during compliance testing. This Recommendation | International Standard: ‒ specifies compliance testing procedures for encoding and decoding using Rec. ITU-T T.800 | ISO/IEC 15444-1 and Rec. ITU-T T.814 | ISO/IEC 15444-15; ‒ specifies codestreams, decoded images, and error metrics to be used with the testing procedures; ‒ specifies ATSs; ‒ provides guidance for creating an encoder compliance test This Recommendation | International Standard does not include the following tests: 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 and responsiveness, under various conditions. Robustness testing: the process of determining how well an implementation processes data which contains errors.
