Ghosting in anaglyphic stereoscopic images

Abstract: Anaglyphic 3D images are an easy way of displaying stereoscopic 3D images on a wide range of display types, e.g. CRT, LCD, print, etc. While the anaglyphic 3D image method is cheap and accessible, its use requires a compromise in stereoscopic image quality. A common problem with anaglyphic 3D images is ghosting. Ghosting (or crosstalk) is the leaking of an image to one eye, when it is intended exclusively for the other eye. Ghosting degrades the ability of the observer to fuse the stereoscopic image and hence the quality of the 3D image is reduced. Ghosting is present in various levels with most stereoscopic displays, however it is often particularly evident with anaglyphic 3D images. This paper describes a project whose aim was to characterize the presence of ghosting in anaglyphic 3D images due to spectral issues. The spectral response curves of several different display types and several different brands of anaglyph glasses were measured using a spectroradiometer or spectrophotometer. A mathematical model was then developed to predict the amount of crosstalk in anaglyphic 3D images when different combinations of displays and glasses are used, and therefore predict the best type of anaglyph glasses for use with a particular display type.© (2004) COPYRIGHT SPIE--The International Society for Optical Engineering.

Image processing system, program, information storage medium, and image processing method

Abstract: An original image area IMR is divided into divided image areas DR 1 to DR 4 , texture coordinates specified by division point coordinates are obtained, and images of the divided image areas DR 1 to DR 4 are mapped onto polygons PL 1 to PL 4 , based on the obtained texture coordinates. The original image area IMR is divided in such a manner that division spacing in a direction DIR 1 towards a vanishing point VP 1 from the original image becomes narrower as the divided image areas are closer to the vanishing point VP 1 and texture coordinates are obtained, to implement correction processing for removing perspective of the original image. Correction processing is performed to remove perspective of images at a base surface of images IL 1 and IR 1 for the left eye and the right eye, the images IL 2 and IR 2 for the left eye and the right eye are generated, and a stereoscopic image is generated by synthesizing (by anaglyph processing) IL 2 and IR 2.

New Methods to Produce High Quality Color Anaglyphs for 3-D Visualization

Abstract: 3D visualization techniques have received gaining interest in recent years. During the last years, several methods for synthesis and projection of stereoscopic images and video have been developed. These include autostereoscopic displays, LCD shutter glasses, polarization based separation and anaglyphs. Among these methods, anaglyph based synthesis of 3D images provides a low cost solution for stereoscopic projection and allows viewing of stereo video content where standard video equipment exists. Standard anaglyph based projection of stereoscopic images, however, usually yields low quality images characterized by ghosting effects and loss of color perception. In this paper, methods for improving quality of anaglyph images, as well as conservation of the image color perception are proposed. These methods include image alignment and use of operations on synthesized depth maps.

Stereoscopic universal digital camera adapter

Abstract: A stereoscopic single digital camera adapter in the form of a quick-snap, center sliding plate (1) and guide track adapter (3) with built-in leveling jacks (10), a horizontal level vial (16) and dead-end stops between 0 and 55 mm, which is similar to the average distance between the center of two human eyes. This pocket-sized universal adapter is for use with digital cameras to better facilitate, and quickly and easily capture very precise quality still pair of images of a scene or a subject by any person. The invention helps to capture a stereo pair of images, one that emulates a left eye view of the intended subject and another that emulates a right eye view of the same scene or subject. The two image pairs can then be downloaded into a computer and /or printed on paper through printing devices or viewed in any desired stereoscopic, anaglyph or interlaced viewing formats.

A cell phone that can take stereo images

Abstract: A cellular terminal includes two cameras (14, 16) which are separated or are separable by a distance suitable for producing a pair of stereo images. The cameras can be oriented to point in substantially the same direction. Image data is derived from the two cameras in store (18, 20; fig.2). The image data is converted to a transmissible form in an image merge and store unit (26; fig.3) and then transmitted via a transmit controller (22; fig.2) and antenna (24; fig 2). The image data may be transmitted as separate images (fig.2). The terminal may be a receiver which can display an anaglyph image.

Stereoscopic video image display device and method

Abstract: PROBLEM TO BE SOLVED: To display color video images for an observer, even in an anaglyph method and reduce a data amount to be transmitted to a display unit during the display of the stereoscopic video image in the stereoscopic video image display device and its displaying method, and further to provide the stereoscopic image display device and its display method unavailable in a conventional methods. SOLUTION: Imaging devices 12, 14, 16 pick up three continuous parallax images. The imaging device 14 photographs an intermediate image between the imaging device 12 and the imaging device 16. The imaging device 12 generates either B signal or R signal, and the imaging device 14 generates G signal; while the imaging device 16 generates the other one of B signal and R signal. A display control device 20 displays each signal on a display device 30. By having an observer, who is wearing a complementary color glasses made up of a red filter and a blue filter views the display unit 30, on one eye light of B signal and G signal are received, while a light of R and G signals is received by the other eye so that a stereoscopic color video image is displayed.

Three-Dimensional Microscopy Image System Based on Depth from Focus

Abstract: Microscope suffers from the problem of limited depth of focus, which precludes the observation of complete image of a three-dimensional object in a single view. In this paper, extending depth of focus by multi-focus image fusion is investigated. The principle of image fusion based on depth of focus is analyzed, and one spatial domain multi-focus algorithm is implemented. Then a multi-focus micro-image fusion algorithm based on area wavelet transform is presented, which offer improved performance over existing algorithms when processing transparent images. In order to obtain 3D structures of the object, Gaussian interpolation algorithm has been selected to interpolate a small number of focus measure values to obtain accurate depth estimates. Based on the above DEM and Montage images, the 3D surface of micro-object is reconstructed by surface rendering algorithm. And the stereo pair images(left and right) and anaglyph image are also emulated.

Method of manufacturing printed matter for stereoscopic vision, and printed matter for stereoscopic vision

Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a printed matter for stereoscopic vision and a printed matter for stereoscopic vision which realize more natural stereoscopic vision. SOLUTION: Images IL1 and IR1 for left eye and right eye for stereoscopic vision are generated. When a plane which is the slant direction to the line of sight direction and established upwardly rather than a body being an object is used as a reference plane BS, the images IL1 and IR1 are subjected to correction processing for eliminating the perspectives of the images in at least the depth direction on the reference plane BS for IL1 and IR1 to generate the images IL2 and IR2 for the left eye and the right eye. By means of anaglyph processing or the like, based on the IL2 and IR2, printed matter for stereoscopic vision is generated. COPYRIGHT: (C)2005,JPO&NCIPI
