Symmetry-based interpolation in images

摘要

The aspects described herein relate to replacing pixels in images in order to remove obstructions from images. In one example, an image of a scene having symmetrical features and image information identifying at least one pixel of the image corresponding to a hole to be filled may be received. This hole may correspond to an obstruction in the image. A set of symmetry axes may be identified based on the symmetrical features. A symmetry map identifying correspondences between different pixels in the image based on the set of symmetry axes may be generated. A correspondence between the at least one pixel corresponding to a hole to be filled and a second pixel of the image is identified based at least in part on the symmetry map and the image information. The at least one pixel may be altered based on the identified correspondence in order to remove the obstruction.

1. A method comprising:
receiving, by one or more computing devices, an image of a scene having symmetrical features; receiving, by the one or more computing devices, image information identifying at least one pixel of the image corresponding to an obstruction in the image; identifying, by the one or more computing devices, a set of symmetry axes based on the symmetrical features of the scene; generating, by one or more computing devices, a symmetry map identifying correspondences between different pixels in the image based on the set of symmetry axes; identifying, by the one or more computing devices, a correspondence between the at least one pixel and a second pixel of the image based at least in part on the symmetry map and the image information; and altering, by the one or more computing devices, the at least one pixel based on the identified correspondence in order to provide an output image where the obstruction appears to be at least partially removed from the image.
