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.
