Method and apparatus for automatic film restoration

摘要

A method and an apparatus for automatic restoration of an image or a sequence of images, e.g. motion picture films, are disclosed, which facilitate removal of artifacts within the image or the sequence of images. The restoration is split into a detection process, a quality control process, and a removal process. In the detection process artifacts in the image or the sequence of images are detected and information about the detected artifacts is stored in a metadata database. In the subsequent quality control process the information about the detected artifacts is reviewed by an operator. In the removal process one or more of the detected artifacts are removed from the image or the sequence of images based on the information about the detected artifacts stored in the metadata database.

1. A method for restoring an image or a sequence of images, the method comprising:
detecting artifact objects in the image or the sequence of images by clustering spurious pixels into potential artifact objects and identifying artifact objects among the potential artifact objects; storing metadata information about the detected artifact objects in a metadata database; performing a quality control process on the metadata information about the detected artifact objects stored in the metadata database; andremoving one or more of the detected artifact objects from the image or the sequence of images based on the metadata information about the detected artifact objects stored in the metadata database;
wherein the quality control process comprises adding metadata information about artifact objects to or removing metadata information about artifact objects from the metadata database; and wherein an artifact object is removed from the metadata database by deleting the metadata information about the artifact object in the metadata database or deselecting the artifact object for removal by setting the value of the removal toggle flag.
