u ⃗ · v ⃗ = u ⃗ · v ⃗ · cos α and hence α = arccos u ⃗ · v ⃗ u ⃗ · v ⃗ = arccos u x · v x + u y · v y u x 2 + u y 2 · v x 2 + v y 2 Euclidean distance between the positions of the two vector origins in the image.
A global reference frame was defined with the and axis parallel and -axis perpendicular to the image plane, with the origin in the centre of the image plane.
(resp., ) is the distance between two adjacent columns (resp., rows) and and correspond to the new position of the origin of the image in the upper left corner.
These results will be evaluated by the operator of phase 1, and in this case the origin of the image, the patient characteristics and the results obtained in the previous evaluation will not be known.
The point ( {I}_{00}^L )and its conjugate point ( {I}_{00}^R )are relocated to the origin in epipolar image space.
We shall look for a biholomorphic mapping from U to the unit disc D which takes 0 to 0. Of course, if there is a biholomorphic map from U to the unit disc at all, there is one that takes 0 to 0 since a linear fractional transformation taking the unit disc D to itself will take any given point to the origin, and in particular the image of 0 to begin with can be moved to the origin.
Binocular parallax is the relative spatial distance between similar points, which share the same physical origin, in the left and right stereo image pairs.
Faced with the presence of an enormous — and rugged — full-length mirror in their enclosure, the animals displayed clear signs of grasping that they themselves were the origin of the images in the glass.
This is given in pixels, si,k= (xi,k, yi,k), where x indicates the column and y is the row of the corresponding point in the image, while the origin is set at the upper-left corner of the image.
The xy-origin of the image is at the top left of the image.
