Abstract
This specification describes technologies relating to digital images. In general, one aspect of the subject matter described in this specification can be embodied in methods that include the actions of receiving a source wide-angle image; identifying one or more locally salient features of the source wide-angle image; calculating a mapping from the source wide-angle image to a two-dimensional mapped wide-angle image according to constraints using the identified one or more spatially variable salient features; and rendering the mapped wide-angle image using the calculated mapping such that the mapped wide-angle image reduces distortion of the locally salient features relative to the distortion of the source wide angle image.
