Özet

The ability to provide a realistic perception of depth is the core added functionality of modern 3D video display systems. At present, there is no standard method to assess the perception of depth in 3D video. Existence of such methods would immensely enhance the progression of 3D video research. This paper focuses on the depth perception assessment in color plus depth representation of 3D video. In this paper, we subjectively evaluate the depth perceived by the users on an auto stereoscopic display, and analyze its variation with the impairments introduced during the compression of the depth images. The variation of the subjective perception of depth is explained based on another evaluation that is carried out to identify the Just Noticeable Difference in Depth (JNDD) perceived by the subjects. The JNDD corresponds to the sensitivity of the observers to the changes in depth in a 3D video scene. Even though only the effects of compression artifacts are considered in this paper, the proposed assessment technique, based on the JNDD values can be used in any future depth perception assessment work.
