AI Technical Summary

Problems solved by technology

A search range selection that is too narrow can lead to an undesired degradation in the quality of the estimated disparity
At the same time, very wide (eg, unconstrained) ranges for stereo matching may add unnecessary computational complexity

Embodiment Construction

[0062] In the following, some aspects of three-dimensional (3D) multi-view applications and the concepts of depth and disparity information closely related thereto are briefly described.

[0063] Stereoscopic video content consists of pairs of offset images that are shown to the viewer's left and right eyes, respectively. These offset images are captured using a specific stereo camera setup, and it assumes a specific stereo baseline distance between the cameras.

[0064] figure 1 A simplified 2D model of such a stereo camera setup is shown. exist figure 1 where C1 and C2 refer to the cameras of the stereo camera setup, more specifically the center positions of the cameras, b is the distance between the centers of the two cameras (i.e., the stereo baseline), f is the focal length of the cameras, and X is the Objects captured in real 3D scenes. A real-world object X is projected to different locations in the images captured by cameras C1 and C2, these locations are x1 and x2...

Abstract

There is provided methods, apparatuses and computer program products for image processing in which a pair of images may be downsampled to lower resolution pair of images and further to obtain a disparity image representing estimated disparity between at least a subset of pixels in the pair of images. A confidence of the disparity estimation may be obtained and inserted into a confidence map. The disparity image and the confidence map may be filtered jointly to obtain a filtered disparity image and a filtered confidence map by using a spatial neighborhood of the pixel location. An estimated disparity distribution of the pair of images may be obtained through the filtered disparity image and the confidence map.

Description

technical field [0001] The invention relates to an apparatus, a method and a computer program for image processing. Background technique [0002] This section is intended to provide a background or context to the invention that is recited in the claims. The description herein may contain concepts that could be pursued, but are not necessarily concepts that have been previously conceived or pursued. Therefore, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section. [0003] Various technologies for providing three-dimensional (3D) video content are currently being researched and developed. In various multiview applications, a viewer can see only one pair of stereoscopic videos from a specific viewpoint, and another pair of stereoscopic videos from a different viewpoint. In some approaches, only a limited number of input views, e....
