ISO/IEC TR 29170-1:2017推荐了图像和图像序列编码系统评估的最佳实践。ISO/IEC TR 29170-1:2017定义了编码系统评估的通用术语表，并将评估方法分为三大类: a） 主观评价； b） 客观评价； c） 计算评估。 除了这些广泛的评估类别外，本文件还讨论了对异常图像（例如高动态范围或高颜色深度）进行编码时应特别注意的事项。 第四个评估类别，硬件复杂性，对于实时或计算复杂的应用程序来说通常很重要；但是，它不在本文件的范围内。

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.
