TLDR
The psychophysical property of the human visual system, that only one high resolution image in a stereo image pair is sufficient for satisfactory depth perception, has been used to further reduce the bit rates in this paper.Abstract:
Stereoscopic sequence compression typically involves the exploitation of the spatial redundancy between the left and right streams to achieve higher compressions than are possible with the independent compression of the two streams. In this paper the psychophysical property of the human visual system, that only one high resolution image in a stereo image pair is sufficient for satisfactory depth perception, has been used to further reduce the bit rates. Thus, one of the streams is independently coded along the lines of the MPEG standards, while the other stream is estimated at a lower resolution from this stream. A multiresolution framework has been adopted to facilitate such an estimation of motion and disparity vectors at different resolutions. Experimental results on typical sequences indicate that the additional stream can be compressed to about one-fifth of a highly compressed independently coded stream, without any significant loss in depth perception or perceived image quality. >read more

Optimal blockwise dependent quantization for stereo image coding
Woontack Woo,Antonio Ortega +1 more
TL;DR: This work addresses the problem of blockwise bit allocation for coding of stereo images and shows how, given the special characteristics of the disparity field, one can achieve an optimal solution with reasonable complexity, whereas in similar problems in motion compensated video only approximate solutions are feasible.

Compression of stereo image pairs and streams
TL;DR: In this paper, the authors exploit the correlations between 3D-stereoscopic left-right image pairs to achieve high compression factors for imageframe storage and image stream transmission, and they find extremely high correlations between left- right frames offset in time such that perspective-induced disparity between viewpoints and motion-induced parallax from a single viewpoint are nearly identical; they coin the term "WoridLine correlation" for this condition.

A hybrid scheme for low bit-rate coding of stereo images
TL;DR: The algorithm effectively combines the simplicity and adaptability of the existing block based stereo image compression techniques with an edge/contour based object extraction technique to determine appropriate compression strategy for various areas of the right image.

Multiple viewpoint rendering for three-dimensional displays
Michael Halle,Stephen A. Benton +1 more
TL;DR: A new algorithm, multiple viewpoint rendering (MVR), is described which produces an equivalent set of images one to two orders of magnitude faster than previous approaches by considering the image set as a single spatio-perspective volume.

Compression and Representation of 3-D Images
TL;DR: More general platform for the 3-D image representation is introduced, aiming to outgrow the framework of 3- D “image” communication and to open up a novel field of technology, which should be called the “spatial’ communication.

Compression Of Stereo Images And The Evaluation Of Its Effects On 3-D Perception
TL;DR: The proposed approach to stereo image coding takes advantage of the singleness of vision property of the human visual system and shows that a stereo image pair, in which one of the images is low-pass filtered and subsampled, is perceived as a sharp 3-D image.

Stereo-enhanced displacement estimation by genetic block matching
TL;DR: In this article, a block based vector field estimation technique based on a genetic algorithm was proposed to accelerate the convergence of the vector field. But the accuracy of the estimation was not compromised.
