信息技术 - 高级图像编码和评估 - 第1部分:编解码器评估指南

[中文适用范围]： 本文档推荐了图像和图像序列编码系统评估的最佳实践。本文档定义了编码系统评估的通用术语，并将评估方法分为三类：a) 主观评估；c) 计算评估；b) 客观评估；除了这些广泛的评估类别外，本文档还讨论了对特殊图像（例如高动态范围或高色深）编码的特殊关注。第四个评估类别——硬件复杂度，通常对于实时或计算复杂的应用很重要；然而，这超出了本文档的讨论范围。 [外文原描述]： 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.
