Assignee: KYOCERA DOCUMENT SOLUTIONS INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 8:
9. A document copy machine comprising:
a scanning element;
logic configured to transform bounding boxes generated by one or both of a region proposal network and a region of interest network by:
a) determining a first set of the bounding boxes exhibiting dense spacing;
b) determining a second set of the bounding boxes exhibiting sparse spacing;
c) executing a first transformation to merge at least some of the bounding boxes exhibiting dense spacing to generate refined bounding boxes, the first transformation comprising:

detecting that a smaller bounding box of the bounding boxes is contained within a larger bounding box of the bounding boxes;
expanding the smaller bounding box to generatean expanded bounding-box; and
on condition that the expanded bounding box is still contained within the larger bounding box, merging the smaller bounding box into the larger bounding box to generate a merged bounding box;
d) executing a second transformation to join at least some of the bounding boxes exhibiting sparse spacing to generate additional ones of the refined bounding boxes;
e) applying an expansion transformation to the refined bounding boxes; and

a classification network configured to utilize the refined bounding boxes to generate one or more classifications of one or more stamps depicted in a scanned image generated by the scanning element; and
logic to apply the classifications to control the scanning element.
