ABSTRACT:
A method backfills areas of an image with synthesized textures. This is realized by selecting a texture exemplar from an image and identifying an area of the image to be backfilled. An estimate of the synthesized texture is generated and predetermined spatial domain constraints are applied to the estimate. The spatially constrained estimate is operated upon by a Fourier transform to create a spectral function. Predetermined spectral domain constraints are applied to the spectral function and an an inverse Fourier transform is performed thereon to produce a synthesized texture. The synthesized texture is inserted into the area of the image to be backfilled if it is determined to be adequate. If the synthesized texture is inadequate, the synthesized texture is put through the synthesis process again until the the texture is adequate for backfilling.
