Abstract
With the appearance of light field displays, users may enjoy a much more natural sensation of 3D experience compared to prior technologies. This type of autostereoscopic, glasses-free visualization allows medical applications to improve both in usability and efficiency. The high angular resolution of medical images is resource-consuming, but can only be reduced while maintaining a sufficient level of overall quality through continuous parallax. A dense image set can also be achieved by applying the synthesis of intermediate views. In this paper we provide the analysis of the effect of reduced angular resolution and image synthesis on Quality of Experience in medical applications. Two separate series of subjective quality assessment measurements were conducted with 20 participants each, one focusing on angular resolution reduction and another one comparing the effect of such reductions with the quality of reconstructed images.
