Abstract: 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.
