“…Three-dimensional (3D) imaging and visualization techniques have been the subject of great interest [1][2][3][4][5][6][7][8]. Among 3D imaging techniques, an integral imaging (II) [9] system is a promising technology because: a) it produces auto-stereoscopic images, thus not requiring special viewing devices, b) it provides the observer images with full parallax and continuous viewing points, c) it is passive; i.e.…”

Because a three-dimensional image can be seen from a desired viewpoint without the aid of special viewing glasses, integral imaging is an ideal way to create 3D auto-stereoscopic images. But 3D displays suffer from crosstalk, an effect that reduces 3D image quality or even inhibits the viewer's ability to correctly perceive depth.Previous optical crosstalk reduction methods decrease the amount of visible crosstalk. However, these methods are not necessarily easy and may not be practical. We describe a new spatial-mapping method based on gradient of elemental image to overcome the problem. This method can eliminate the crosstalk to a great extent. Experimental results indicating the advantages of this method are shown.

“…The displayed images can have entertainment or information value or even be aimed at the diffusion of scientific results. 1 The information society increasingly demands the display not only of plane images but also of threedimensional (3D) images or even movies, [2][3][4][5] with continuous perspective information. Although the search for optimum 3D imaging and display techniques has been the subject of research for more than a century, 6 only in the past few years has technology approached the level required for realization of 3D imaging systems.…”

Multifacet structure of observed reconstructed integral images

et al. 2005

Three-dimensional images generated by an integral imaging system suffer from degradations in the form of grid of multiple facets. This multifacet structure breaks the continuity of the observed image and therefore reduces its visual quality. We perform an analysis of this effect and present the guidelines in the design of lenslet imaging parameters for optimization of viewing conditions with respect to the multifacet degradation. We consider the optimization of the system in terms of field of view, observer position and pupil function, lenslet parameters, and type of reconstruction. Numerical tests are presented to verify the theoretical analysis.

“…From this original proposal, other studies have been performed in order to solve the resolution limitation of II 6-10 , increase depth of focus [11][12][13] , and other analysis and challenges in II [14][15][16][17] , because of the interest of improving 3D image quality. In this work, we review the scaling problem in 3D II that was studied and solved by controlling the spatial ray sampling rate of elemental image arrays in the pickup procedure 18 .…”

Digital magnification of three dimensional integral imaging using image interpolation algorithms

We can enlarge or reduce three-dimensional integral imaging images by using an optical multi-pickup method. We used the moving array-lenslet technique (MALT) to increase the spatial ray sampling rate of elemental images in the optical method. In this paper, we are proposing a digital magnification method to increase the spatial ray sampling rate without lens movement. The major drawback of the optical technique is the complexity due to the small lenslet movement. We used four popular two dimensional (2D) magnified interpolation methods, as: linear, cubic, spline and nearest. We compared the reconstructed integral imaging images using optical and digital magnification methods. When use the optical and digital magnification are used in a sequence, we can reduce the number of pickup procedures for the optical method to a forth while we can see almost the same resolution quality of the reconstructed integral imaging images.
