Abstract: First visual information defining the visual content in a first projection may be accessed. Second visual information defining lower versions of the visual content in the first projection may be accessed. A transformation of the visual content from the first projection to a second projection may be determined. The transformation may include a visual compression of a portion of the visual content in the first projection. The portion may be identified. An amount of the visual compression of the portion may be determined. One or more lower resolution versions of the visual content may be selected. The visual content may be transformed using the one or more lower resolution versions of the visual content.

Abstract: Images of a scene may be captured by a set of image capture devices. Overlapping areas of the images may be identified based on the topology of the set of image capture devices. Frontiers within the overlapping areas of the images may be identified based on borders of the images. Sample points for the images may be distributed along the frontiers. Warp parameters including an anti-symmetric warping portion and a symmetric warping portion may be determined at the sample points. Displacement values may be determined at the sample points based on the warp parameters. Warp maps for the images may be determined based on diffusion of the displacement values. Displacement maps for the images may be determined based on interpolation of the warp maps. The images may be modified based on the displacement maps.
