US Patent 10353997 Freeform annotation transcription

A freeform annotation in a print medium may be captured and converted to a digital annotation for association with a corresponding digital medium. The freeform annotations, which may be created by a human in the print medium, may be captured as an image by a camera. The image may be analyzed to determine a particular freeform annotation and associate the freeform annotation with text or objects in content of the print medium to create an anchor location for the freeform annotation. The location of the freeform annotation in the print medium may be mapped to a location in a corresponding digital medium. A digital version of the freeform annotation may be configured for display in the location of the corresponding digital medium.
