Aerial video registration is traditionally performed using 2-d transforms in the image space. For scenes with large 3-d relief, this approach causes parallax motions which may be detrimental to image processing and vision algorithms further down the pipeline. A novel, automatic, and online video registration system is proposed which renders the scene from a fixed viewpoint, eliminating motion p...

We propose a framework for depth estimation from a set of calibrated images, captured with a moving camera with varying parameters. Our framework respects the physical limits of the camera, and considers various effects such as motion parallax, defocus blur, zooming and occlusions which are often unavoidable. In fact, the stereo [1] and the depth from defocus [2] are essentially special cases i...

In this review, studies of the role of head movements in generating motion parallax which is used in depth perception are examined. The methods used and definitiveness of the results vary with the animal groups studied. In the case of insects, studies which quantify motor outputs have provided clear evidence that motion parallax evoked by head movements is used for distance estimation and depth...

This paper is a continuation of our previous analysis (i.e. Turyshev 2002a, 2002b) of the relativistic stellar aberration requirements for the Space Interferometry Mission (SIM). Here we have considered a problem of how the expected astrometric accuracy of parallax determination will constrain the accuracy of the spacecraft navigation. We show that effect of the spacecraft’s navigational errors...

A field star serendipitously observed in a parallax program proved to have a proper motion of 562 mas yr and a parallax of 82 ± 2 mas. The star is identified with 2MASS J07003664+3157266. A Keck LRIS spectrum shows its spectral type to be L3.5, as expected from its infrared and optical colors and absolute magnitude. This object had not been previously recognized as an L dwarf, perhaps because o...

Absolute range detection has been a long-time objective of studies focused on achieving stereo computer vision. Many researchers have attempted to emulate some part of the human stereo system, most commonly motion parallax. These attempts, however, have concluded that motion parallax is not a reliable source of input for systems attempting range measurements and, in fact, often worsens object s...

In this paper a binary relation between L-sets, called attachment, is defined by means of a suitable family of completely coprime filters in L. Examples are given using several kinds of lattice-ordered algebras and a class of attachments is determined whose elements generalize Pu-Liu’s quasi-coincidence relation. Mapping any L-set on X to the set of the attached L-points one gets a frame map fr...
