Mapping the disk to a square method in Matlab

Completed Posted 4 years ago Paid on delivery
Completed Paid on delivery

Preamble:

- This is a small part of a non-commercial art project with a fixed budget of 100 EUR but no strict due date or deadline. A sufficient time intervall would be completion in 2-3 weeks.

- Making higher price bids than the budget or low price bids without reading the description and demanding more later is worthless and is only a waste of time for all stakeholders.

- Demanding a milestone release without me inspecting and testing the Matlab code will not be accepted.

In the publication

Chamberlain Fong: Elliptification of Rectangular Imagery. 2019. [login to view URL]

several analytical methods were described for (non-conformal) mapping a disk to a square disk2sq (plus the inverse mappings sq2disk). In his blog

the author described the example of the "Elliptical Grid mapping" (see also: "Elliptification of Rectangular Imagery", page 5 last method of the publication) additionally with some C++ code that should be used to develop a Matlab implementation with meshgrid and interp2.

Mastering the analytical part is the necessary condition but the image mapping must be in a high quality (no pixel blocks, unsharp areas or other artifacts) which is the sufficient condition of the task. Therefore meshgrid & interp2 must be included which also assures that the output image size can be set. Other pages of the blog of C. Fong shows that such high quality mappings are possible (with his C++ implementations).

There is some matlab code and images with a hyperbolic disk as examples for input in the disk2square part.
