NPR-ISO/IEC-TR 29170-1 recommends best practices for coding system evaluation of images and image sequences. This document 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.
