ABSTRACT:
The present invention relates to an apparatus and methods for performing image restoration. More specifically, the present invention relates to an apparatus and methods which are capable of quickly restoring various sizes of selected areas of an image. In one embodiment, a user may select or mark a target region in an image which is to be restored. A source window may then be generated and a pixel from within the target region may be selected for restoration. The intensity distribution of pixels surrounding the selected pixel may be compared with other pixels in the image and a pixel to be used for restoration of the selected pixel may be chosen based on the comparison of the intensity distributions. Once a pixel is chosen for restoration, the selected pixel and its surrounding pixels may be restored using the intensity distribution of the chosen pixel and its surrounding pixels. The method may continue in this manner until all pixels within the target region have been restored.
