A survey of 3D image quality metrics for relief print evaluation

This paper aims to give a survey of research related to the assessment of image quality metrics of 2.5D and 3D prints. Future research will focus on the ability of combining relief and glossiness in printouts created by a prototype printer that uses multiple layers of ink and varnish. Reproducing these relief or 2.5D surfaces brings out the challenge of evaluating the quality of the outcome. Although, for some decades, active research has been done on 2D image quality assessment, quality evaluation of images in a higher dimension is yet in an early stage. Currently, there are no image quality metrics defined for relief prints and much about their perception is still unknown. As a first step to come up with such metrics, the following survey explores research on the quality assessment of 3D prints, objects, computer simulations and television to relate to future image quality metrics for relief prints.
