ORQA: Objective Reflection Quality Assessment

We present ORQA (Objective Reflection Quality Assessment), a method to objectively assess shape quality from reflection line renderings. The goal of ORQA is to correctly order existing comparable reflection line renderings according to perceived shape quality. Surface quality information is extracted from directional changes of the reflection lines. Relative importance on the directional changes and reflection line length are key aspects of scoring. ORQA is fast, stable and generalises well over various datasets.
