Abstract
Methods and systems for determining information for a specimen are provided. One system includes a computer subsystem configured for removing one or more patterns in a specimen image that do not touch a defect detected in the specimen image thereby generating a modified specimen image. The computer subsystem is also configured for generating one or more hash codes for the modified specimen image. In addition, the computer subsystem is configured for assigning the specimen image to one of multiple groups based on a distance between the one or more hash codes and one or more other hash codes generated for a second modified specimen image generated for a second specimen image.
