Patent ID: 11941904

Abstract:
A computer-implemented method (300) for extracting content (302) from a physical writing surface (304), the method (300) comprising the steps of:(a) receiving a reference frame (306) including image data relating to at least a portion of the physical writing surface (304), the image data including a set of data points;(b) determining an extraction region (308), the extraction region (308) including a subset of the set of data points from which content (302) is to be extracted;(c) extracting content (302) from the extraction region (308) and writing the content (302) to a display frame (394);(d) receiving a subsequent frame (406) including subsequent image data relating to at least a portion of the physical writing surface (304), the subsequent image data including a subsequent set of data points;(e) determining a subsequent extraction region (408), the subsequent extraction region (408) including a subset of the subsequent set of data points from which content (402) is to be extracted; and(f) extracting subsequent content (402) from the subsequent extraction region (408) and writing the subsequent content (402) to the display frame (394).
