Image processing apparatus and method
TLDR
In this article, a robust, accurate image matching can be done by making dynamic matching between all pixels on a scan line in the images captured by the cameras, by determining a similarity in brightness and color components at the pixel positions and a parallax between the corrected object images.Abstract:
Directions normal to images of an object captured by at least two cameras from different points of view are aligned with each other to form corrected object images, and a correspondence is determined between at least one pixel position on a horizontal line in one of the corrected object images and at least one pixel position on the same horizontal line in another of the corrected object images. The correspondence is determined by determining a similarity in brightness and color components at the pixel positions and a parallax between the corrected object images A robust, accurate image matching can be done by making dynamic matching between all pixels on a scan line in the images captured by the cameras.read more

Method and apparatus for generating multi-viewpoint depth map, method for generating disparity of multi-viewpoint image
TL;DR: In this paper, a method for generating a disparity of a multi-viewpoint image is presented, which includes the steps of: (a) acquiring an image and depth information by using a depth camera; (b) estimating coordinates of the same point in a space in the plurality of images by using the acquired depth information; (c) determining disparities in the images with respect to in the same points by searching a predetermined region around the estimated coordinates; and (d) generating a multiviewpoint depth map by using determined disparities.

Image Processing Apparatus, Image Processing Method, and Program
TL;DR: In this article, a high-frequency component is extracted from a brightness signal for a neighboring pixel to generate the focus information on the neighboring pixel, which is then used to calculate the depth value of each pixel using a coefficient based on the illumination component.

Computational vision and regularization theory
TL;DR: Descriptions of physical properties of visible surfaces, such as their distance and the presence of edges, must be recovered from the primary image data and algorithms and parallel analog circuits that can solve ‘ill-posed problems’ and which are suggestive of neural equivalents in the brain are proposed.
