“…Indeed, in other studies we have demonstrated that depth information need not be complete or accurate to generate stereoscopic images with effective stereoscopic depth [5] [6]. Accordingly, in this study we investigated whether our previous observations extended to colour component-based depth maps.…”

“…Previously, we have shown that stereoscopic images generated using depth maps with sparse or even inaccurate depth information at edges and object boundaries, can still provide higher perceived depth than their two-dimensional counterparts [5] [6]. However, we also found that the use of these surrogate 1 depth maps could, in certain cases, be accompanied by a decrease in image quality due to geometric distortions at object boundaries; this loss of image quality occurred even when the surrogate depth maps were "smoothed" before rendering [7].…”

The ability to convert 2D video material to 3D would be extremely valuable for the 3D-TV industry. Such conversion might be achieved using depth maps extracted from the original 2D content. We previously demonstrated that surrogate depth maps with limited or imprecise depth information could be used to produce effective stereoscopic images. In the current study, we investigated whether gray intensity images associated with the Cr colour component of standard 2D-colour video sequences could be used effectively as surrogate depth maps. Colour component-based depth maps were extracted from ten video sequences and used to render images for the right-eye view. These were then combined with the original images for the left-eye view to form ten stereoscopic test sequences. A panel of viewers assessed the depth quality and the visual comfort of the synthesized test sequences and, for comparison, of monoscopic and camera-captured stereoscopic versions of the same sequences. The data showed that the ratings of depth quality for the synthesized test sequences were higher than those of the monoscopic versions, but lower than those of the camera-captured stereoscopic versions. For visual comfort, ratings were lower for the synthesized than for the monoscopic sequences but either equal to or higher than those of the camera-captured versions.

“…Although many researchers have been delving into depth reconstruction required for solving the 2D-to-3D conversion problem [1][2][3][4][5][6][7], it is still difficult to perfectly recover the real depth information from 2D image/video. Fortunately, in case of the 2D-to-3D conversion application, pseudo 3D effect can be generated by perceptual depth which may be much different from real depth.…”

A novel 2D-to-3D conversion technique based on relative height-depth cue

We present a simple depth estimation framework for 2D-to-3D media conversion. The perceptual depth information from monocular image is estimated by the optimal use of relative height cue, which is one of well-known depth recovery cues. The height depth cue is very common in photographic images. We propose a novel line tracing method and depth refinement filter as core of our depth estimation framework. The line tracing algorithm traces strong edge positions to generate an initial staircase depth map. The initial depth map is further improved by a recursive depth refinement filter. We present visual results from depth estimation and stereo image generation.
