The images can be taken from a different point of view, at different times, or with objects in the scene in general motion relative to the camera(s). The correspondence problem can occur in a stereo situation when two images of the same scene are used, or can be generalised to the N-view correspondence problem.

The method of images (or method of mirror images) is a mathematical tool for solving differential equations, in which boundary conditions are satisfied by combining a solution not restricted by the boundary conditions with its possibly weighted mirror image. Generally, original singularities are inside the domain of interest but the function is ...
Solve an equation [14] Also suggested: Look for a pattern [15] Draw a picture [16] Solve a simpler problem [17] Use a model [18] Work backward [19] Use a formula [20] Be creative [21] Applying these rules to devise a plan takes your own skill and judgement. [22] Pólya lays a big emphasis on the teachers' behavior.
To solve for the model parameters that fit our data, we might be able to invert the matrix to directly convert the measurements into our model parameters. For example: p = F − 1 d obs {\displaystyle p=F^{-1}d_{\text{obs}}} A system with five equations and five unknowns is a very specific situation: our example was designed to end up with this ...
Astrometric solving or Plate solving or Astrometric calibration of an astronomical image is a technique used in astronomy and applied on celestial images. Solving an image is finding match between the imaged stars and a star catalogue. The solution is a math model describing the corresponding astronomical position of each image pixel. [1]
Thus, if one can solve for one iterated function system, one also has solutions for all topologically conjugate systems. For example, the tent map is topologically conjugate to the logistic map. As a special case, taking f(x) = x + 1, one has the iteration of g(x) = h −1 (h(x) + 1) as g n (x) = h −1 (h(x) + n), for any function h.
A demonstration of visual cryptography. When two same-sized images of apparently random black-and-white pixels are superimposed, the Wikipedia logo appears. In this example, the binary image has been split into two component images. Each component image has a pair of pixels for every pixel in the original image. These pixel pairs are shaded ...
