“…Thirdly, it would be valuable to understand the characteristics or profiles of different objective quality factors (e.g. artifact clusters [2]) on a descriptive scale. Ultimately, this could lead to the novel approach of development of quality metric going beyond the level-of apparent features of stimuli.…”

“…In mobile 3DTV systems, produced quality is characterized by various factors along the production chain on the levels of content, media and network [7]. Impairments like blocking artifacts or frame loss occur, propagate jointly over the chain and can influence the user's experienced quality [2,7,32].…”

“…Such thoughts were described as: ' [ ' (male, 39). In addition, several remarks about disparity errors between the two views were specified (seeing in two, shadows, colorerrors between views, see-through objects) underlining the common impairments of parallax barrier display technology [2]. Spatial quality was strongly defined by the factors of excellence (accuracy, inaccuracy).…”

Perceptual quality evaluation experiments are used to assess the excellence of multimedia quality. However, these studies disregard qualitative experiential descriptions, interpretations, and impressions of quality. The goal of this paper is to identify general descriptive characteristics of experienced quality of 3D video on mobile devices. We conducted five studies in which descriptive data was collected after the psychoperceptual quality evaluation experiment. Qualitative semi-structured interviews and written attribute description tasks were conducted with over 90 naïve participants. The experiments contained an extensive and heterogeneous set of produced quality by varying content, level of depth, compression and transmission parameters, and audio and display factors for 3D. The results showed that quality of experience is constructed from four main components, 1) visual quality, 2) viewing experience, 3) content, and 4) quality of other modalities and their interactions.

“…The models based on neurobiology estimate the actual low-level process in human visual system including the eye and optical nerve. However, these models are not widely used, because of their complexity [36]. Psychophysical HVS-based models are implemented in a sequential process that includes luminance masking, color perception analysis, frequency selection, contrast sensitivity implementation (based on the contrast sensitivity function CSF [37]) and modeling of masking and facilitation effects [38].…”

View-plus-depth is a scene representation format where each pixel of a color image or video frame is augmented by per-pixel depth represented as gray-scale image (map). In the representation, the quality of the depth map plays a crucial role as it determines the quality of the rendered views. Among the artifacts in the received depth map, the compression artifacts are usually most pronounced and considered most annoying. In this article, we study the problem of post-processing of depth maps degraded by improper estimation or by block-transformbased compression. A number of post-filtering methods are studied, modified and compared for their applicability to the task of depth map restoration and post-filtering. The methods range from simple and trivial Gaussian smoothing, to in-loop deblocking filter standardized in H.264 video coding standard, to more comprehensive methods which utilize structural and color information from the accompanying color image frame. The latter group contains our modification of the powerful local polynomial approximation, the popular bilateral filter, and an extension of it, originally suggested for depth super-resolution. We further modify this latter approach by developing an efficient implementation of it. We present experimental results demonstrating high-quality filtered depth maps and offering practitioners options for highest-quality or better efficiency.
