信息技术 JPEG2000图像编码系统 第4部分:一致性测试

[中文适用范围]： 本建议书 | 国际标准1规定了框架、概念、测试方法，以及声称符合 ITU-T T.800 建议书 | ISO/IEC 15444-1 或 ITU-T T.814 建议书 | ISO/IEC 15444-15 所要达到的标准。它提供了一个框架，用于指定抽象测试套件（ATS）并定义合规性测试期间要遵循的程序。 本建议书 | 国际标准： ‒ 规定了使用 ITU-T T.800 建议书 | ISO/IEC 15444-1 和 ITU-T T.814 建议书 | ISO/IEC 15444-15 进行编码和解码的合规性测试程序； ‒ 规定了测试程序要使用的码流、解码图像和错误指标； ‒ 规定了 ATS； ‒ 为创建编码器合规性测试提供指导 本建议书 |国际标准不包括以下测试：验收测试：确定实施是否满足验收标准的过程，并允许用户确定是否接受实施。这包括规划和执行几种测试（例如功能、质量和速度性能测试），以证明实施满足用户要求。性能测试：在各种条件下测量被测实施 (IUT) 的性能特征，例如其吞吐量和响应能力。稳健性测试：确定实施处理包含错误的数据的能力的过程。 [外文原描述]： This document1 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 document: ‒ 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 document 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. 1 This document includes an electronic attachment with the codestreams used in the application of the procedures described the Specification.
