1. A system for performing image-based diagnosis of a machine, comprising:
- a database containing a plurality of historical images taken from a plurality of machines, the plurality of historical images comprising a plurality of ideal images generated from the plurality of machines using all possible machine settings and a plurality of artifact images generated from the plurality of machines, each of the artifact images having known faults associated therewith and a corresponding corrective action for repairing the faults; and
a diagnostic unit for diagnosing a new artifact image from a machine having an unknown fault, the diagnostic unit comprising a diagnostic image processor comprising means for finding an ideal image from the plurality of historical images that most closely matches the new artifact image, means for assigning an artifact category to the new artifact image based on the matched ideal image, and means for extracting an artifact feature from the new artifact image according to the assigned category; and
a diagnostic fault isolator comprising means for generating a plurality of metrics for the extracted artifact feature and means for applying the plurality of metrics to identify an artifact image from the plurality of historical images that most closely matches the new artifact image and a corrective action for repairing the unknown fault.

Abstract
The present invention discloses a system and method for performing image-based diagnosis. In this invention, historical artifact images and corresponding actions for repairing the artifacts are acquired and stored in a database. The database of historical artifact images and corresponding actions is used to diagnose an incoming artifact image having an unknown fault.

11. A method for performing image-based diagnosis of a machine, comprising the steps of:
-
obtaining a plurality of historical images taken from a plurality of machines, the plurality of historical images comprising a plurality of ideal images generated from the plurality of machines using all possible machine settings and a plurality of artifact images generated from the plurality of machines, each of the artifact images having known faults associated therewith and a corresponding corrective action for repairing the faults; receiving a new artifact image from a machine having an unknown fault; finding an ideal image from the plurality of historical images that most closely matches the new artifact image; assigning an artifact category to the new artifact image based on the ideal image that most closely matches the new artifact image; generating a plurality of metrics for the artifact category assigned to the new artifact image; and using the plurality of metrics to identify an artifact image from the plurality of historical images that most closely matches the new artifact image and a corrective action for repairing the unknown fault. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
