Image stitching techniques produce an image with wide field-of-view by aligning multiple images with narrow field-of-view. While conventional algorithms successfully stitch images with small parallax, structure misalignment may occur when input images contain large parallax. This paper presents an image stitching algorithm which aligns images with large parallax by regional linear warping. To t...

Temporal characteristics of depth perception from motion parallax were examined by modulating parallax intermittently while observers moved their head side to side. In Experiment 1, parallax of a fixed value was introduced only for the central 1/6 to 5/6 portion of each component head movement. It was found that the perceived depth was proportional to the temporal average of parallax-specified ...

Although motion parallax is closely associated with observer head movement, the underlying neural mechanism appears to rely on a pursuit-like eye movement signal to disambiguate perceived depth sign from the ambiguous retinal motion information [Naji, J. J., & Freeman, T. C. A. (2004). Perceiving depth order during pursuit eye movement. Vision Research, 44, 3025-3034; Nawrot, M. (2003). Eye mov...

Relief mosaics are collections of registered images that extend traditional mosaics by supporting motion parallax. A simple parallax interpolation algorithm based on computed correspondence information allows high quality blurfree and ghost-free mosaics to be created using images from moving hand-held cameras that would not be suitable for traditional mosaicing. The renderer can also display lo...

This paper improves per-pixel displacement mapping algorithms. First we review the previous work including bump, parallax, and relief mapping, and also sphere tracing. Then we propose a new iterative algorithm based on parallax mapping, which takes into account the surface slope represented by the stored normal vector. We show that the new method is much better than parallax mapping, however a ...

It has been argued that when an observer moves, a contingent retinal-image motion of a stimulus would strengthen the perceived glossiness. This would be attributed to the veridical perception of three-dimensional structure by motion parallax. However, it has not been investigated whether the effect of motion parallax is more than that of retinal-image motion of the stimulus. Using a magnitude e...

The period{luminosity relation of Cepheids is calibrated on the basis of the Hipparcos trigonometric parallax values, using data on Cepheids within one kiloparsec. It is shown that the milliarcsec-size apparent orbit of Cepheids belonging to binary systems has an unfavourable innuence on the parallax determination. About two third of the sample studied here have physical companion(s). The true ...

In a neutral particle gas detector, the parallax error resulting from the perpendicular projection on the detection plane or wire of the radial particle trajectories emanating from a point like source (such as a scattering sample) can significantly spoil the apparent angular resolution of the detector. However, as we will show, the information is not lost. We propose an off line data treatment ...
