The warping function modifies picture geometry so that it matches the curve of the projection surface. The elastic torsion of a bar can be described also in formulation of warping function. The function f is called the warping function of the warped product [8].
Warping an image with a combination of warping functions
ActiveUS12620052B1Image analysisGeometric image transformationPattern recognitionComputer graphics (images)
A method includes obtaining an image that includes a plurality of pixels. The method includes identifying a first subset of the plurality of pixels that defines a particular geometry that a user of the electronic device is currently focusing on. The method includes warping the first subset of the plurality of pixels according to a first warping function that is based on a movement of the electronic device. The method includes warping a second subset of the plurality of pixels, that is different from the first subset, according to a second warping function that is different from the first warping function.
