A three-dimensional (3D) cursor for autostereoscopic 3D displays was proposed. The cursor is based on voxel patterns. In the experiments, the cursor position is interactively controlled in 3D by a computer mouse with a scroll wheel. A computer progra

We measured vertical and horizontal displacements of distant objects based on the moiré effect. The grid attached to the object was photographed and recorded on video camera. The video was processed later in the lab. The method is self-calibrated an

A geometric model of an autostereoscopic 3D display is described herein. This model is based on the geometry of typical display devices and on the projective transformations that provide periodicity in the projective space. The formulas for the trans

The experimental measurements of the amplitude, period, and orientation of the moiré patterns in a digital autostereoscopic barrier-type 3D display are presented as functions of the angle across a wide angular range with a small increment. The slope

The wavelet analysis of the integral images can be used in extraction of the depth of the photographed/synthesized 3D objects. The result of the analysis, however, depends on the colour/texture of the object and thus can be ambiguous. In this paper,

The book describes not only 2D moiré patterns, but also explores the moiré effect in other dimensions, such as 1D and 3D (volumetric moiré patterns). It also explains the time-dependent moiré effect, including its spectral trajectories. The book

Multiview wavelets based on voxel patterns of autostereoscopic multiview three-dimensional (3D) displays are proposed. Direct and inverse continuous wavelet transforms of binary and grayscale multiview images were performed. With modified wavelet coe

We describe an optical phenomenon of unmovable moiré patterns in sliding (moving) grids and gratings. The phenomenon was observed visually in the planar straight movement of the black-and-white gratings with a period of several mm. This is a velocit
