Abstract
A system and method for removing optical iridescent artifacts in an image includes scanning an article having a transparent and reflective surface to create the image, identifying potential optical iridescent artifacts in the image resulting from the scan using a search pattern on the image of the article, confirming through a color analysis operation that the potential optical iridescent artifacts discovered along the search pattern are optical iridescent artifacts and not printed on the article and removing the confirmed iridescent artifacts from the image.
Claims24
A method of removing optical iridescent artifacts that appear in scanned image of an article having a transparent and reflective surface comprising:
- identifying potential optical iridescent artifacts in the image resulting from the scan using a search pattern on the image of the article;
- confirming through a color analysis operation that the potential optical iridescent artifacts discovered along the search pattern are optical iridescent artifacts and not printed on the article;
- and
- removing the confirmed iridescent artifacts from the image.
An apparatus for removing optical iridescent artifacts that appear in scanned image of an article having a transparent and reflective surface, comprising:
- a processor capable of executing instructions:
- a memory holding instructions when executed on the processor instruct a scanner to identify potential optical iridescent artifacts in the image resulting from the scan using a search pattern on the image of the article, confirm through a color analysis operation that the potential optical iridescent artifacts discovered along the search pattern are optical iridescent artifacts and not printed on the article and remove the confirmed iridescent artifacts from the image.
An apparatus for removing optical iridescent artifacts that appear in an image, comprising:
- means for scanning an article having a transparent and reflective surface to create the image;
- means for identifying potential optical iridescent artifacts in the image resulting from the scan using a search pattern on the image of the article;
- means for confirming through a color analysis operation that the potential optical iridescent artifacts discovered along the search pattern are optical iridescent artifacts and not printed on the article;
- and
- means for removing the confirmed iridescent artifacts from the image.
A computer program product, tangibly stored on a computer readable medium, for removing optical iridescent artifacts that appear in scanned image of an article having a transparent and reflective surface, comprising instructions operable to cause a programmable processor to:
- identify potential optical iridescent artifacts in the image resulting from the scan using a search pattern on the image of the article;
- confirm through a color analysis operation that the potential optical iridescent artifacts discovered along the search pattern are optical iridescent artifacts and not printed on the article;
- and
- remove the confirmed iridescent artifacts from the image.
