Abstract

A method comprising determining a mapping between a first image location at a first image surface, associated with a portion of an image, and a second image location at a second image surface, associated with a transformed version of the portion of the image. Determining the mapping comprises applying an analytical stereographic projection based on a geometric relationship between the first image surface and the second image surface. Image data representing the image is obtained, and comprises pixel data for a plurality of pixel locations. A portion of the pixel data for use in generating transformed pixel data for the second image location is identified, based on the first image location, and used to generate transformed pixel data for the second image location.

A method comprising:

determining a mapping between a first image location at a first image surface, associated with a portion of an image, and a second image location at a second image surface, associated with a transformed version of the portion of the image, the determining the mapping comprising applying an analytical stereographic projection based on a geometric relationship between the first image surface and the second image surface;
obtaining image data representing the portion of the image, the image data comprising pixel data for a plurality of pixel locations within the portion of the image;
based on the first image location, identifying a portion of the pixel data for use in generating transformed pixel data for the second image location;
and
processing the image data to generate transformed image data representing the transformed version of the portion of the image, the processing the image data comprising processing the portion of the pixel data to generate the transformed pixel data for the second image location.
