This paper proposes a novel 2D-to-3D conversion system based on visual attention analysis. The system was able to
generate stereoscopic video from monocular video in a robust manner with no human intervention. According to our
experiment, visual attention information can be used to provide rich 3D experience even when depth cues from
monocular view are not enough. Using the algorithm introduced in the paper, 3D display users can watch 2D media in
3D. In addition, the algorithm can be embedded into 3D displays in order to deliver better viewing experience with more
immersive feeling. Using visual attention information to give a 3D effect is first tried in this research as far as we know.
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.
Due to subtle misalignment of optical components in the fabrication process, images projected by an optical light
modulator have severe line artifact along the direction of the optical scan. In this paper, we propose a novel methodology
to calibrate the modulator and generate the compensate image for the misaligned optical modulator in order to eliminate
the line artifact. A camera system is employed to construct Luminance Transfer Function (LTF) that characterizes the
optical modulator array. Spatial uniformity is obtained by redefining the dynamic range and compensating the
characteristic curvature of the LTF for each optical modulator array element. Simulation results show significant
reduction in the visibility of line artifact.
