Finding orientation and date of hardcopy medium
View Patent ↗A method of determining the image capture date of scanned hardcopy medium, includes scanning hardcopy medium that includes at least one index print(s) to produce scanned digital images; detecting one or more index prints from among the scanned digital images; identifying thumbnail images contained within the one or more index prints; determining an image capture date for each index print and associating the image capture date with the thumbnail image(s) contained within that index print; matching a scanned digital image to a thumbnail image from the one or more index prints; associating the date from the thumbnail image to the scanned digital image that matches the thumbnail image; and storing the date in association with the scanned digital image that matches the thumbnail image.
1. A method of determining the image capture date of scanned hardcopy medium, comprising:
(a) scanning hardcopy medium that includes at least one index print(s) to produce scanned digital images;
(b) detecting one or more index prints from among the scanned digital images;
(c) identifying thumbnail images contained within the one or more index prints;
(d) determining an image capture date for each index print and associating the image capture date with the thumbnail image(s) contained within that index print;
(e) matching a scanned digital image to a thumbnail image from the one or more index prints, including:
(i) extracting features from the scanned digital image;
(ii) extracting thumbnail features from the thumbnail images; and
(iii) comparing the features and the thumbnail features to find a matching thumbnail image with a scanned digital image;
(f) associating the date from the thumbnail image to the scanned digital image that matches the thumbnail image;
(g) storing the date in association with the scanned digital image that matches the thumbnail image; and
(h) organizing the scanned digital image in accordance with the determined date.
2. The method of claim 1 , further including presenting the scanned digital image to a human operator for verification.
3. The method of claim 1 , further including printing, emailing, or otherwise transmitting the scanned digital image and the associated date.
4. A method of determining the image capture date and orientation of a scanned hardcopy medium, comprising:
(a) scanning hardcopy medium that includes at least one index print(s) to produce scanned digital images;
(b) detecting one or more index prints from among the scanned digital images;
(c) identifying thumbnail images contained within the one or more index prints;
(d) determining an orientation for each index print and associating the image capture date with the thumbnail image(s) contained within that index print;
(e) matching a scanned digital image to a thumbnail image from the one or more index prints;
(f) associating the orientation from the thumbnail image to the scanned digital image that matches the thumbnail image, including rotating the scanned digital image in accordance with the determined orientation;
(g) storing the orientation in association with the scanned digital image that matches the thumbnail image; and
(h) printing the rotated scanned digital image or transmitting the rotated scanned digital image to a display device.
5. The method of claim 4 , wherein step (e) further includes:
extracting features from the scanned digital image;
extracting thumbnail features from the thumbnail images; and
(iii) comparing the features and the thumbnail features to find a matching thumbnail image with a scanned digital image.
6. The method of claim 4 , further including presenting the rotated scanned digital image to a human operator for verification.
7. The method of claim 4 , further including printing, emailing, or otherwise transmitting the rotated scanned digital image.
