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.

Abstract: A first image sensor may generate images capturing a first portion of a capture field. The capture of images by the first image sensor may be characterized by a first rolling shutter direction. A second image sensor may generate images capturing a second portion of the capture field. The capture of images by the second image sensor may be characterized by a second rolling shutter direction. The first portion may be adjacent to the second portion. The first rolling shutter direction may be parallel to and the same as the second rolling shutter direction. A first image may be obtained from the first image sensor. A second image may be obtained from the second image sensor. A stitched image may be generated based on the first image and the second image.
