Image enhancement system

A method of delivering presentation information disposed on a surface to an electronic device, comprising:

• performing, by a controller, a calibration process, comprising:
• capturing, by a camera device, a first image of a surface;
• determining corners of the surface in the first image;
• and
• determining size and shape of a canvas image having determined corners;
• and
• performing, by the controller, a canvas generation process, comprising:
• capturing, by the camera device, a second image of the surface, wherein the second image comprises presentation information that is disposed on at least a portion of the surface, and a portion of a presenter that is disposed between the camera device and the surface;
• performing a presenter segmentation process, comprising:
• detecting the portion of the presenter in a third image that is derived from the second image, wherein the third image is a lower resolution version of the second image;
• and
• generating a presenter mask that is used to define pixels in the second image that are associated with the detected portion of the presenter;
• performing a canvas reconstruction process, comprising:
• replacing the pixels in the second image that are associated with the detected portion of the presenter within the presenter mask to form a reconstructed canvas image;
• performing a presentation information segmentation process, comprising:
• generating a presentation information mask that includes pixels in the reconstructed canvas image that contain portions of the presentation information;
• and
• performing a background reconstruction process, comprising:
• reconstructing the pixels in the reconstructed canvas image that contain the portion of the presentation information to form a canvas background image.

A system for delivering presentation information positioned on a surface to an electronic device, the system comprising:

• a camera device;
• and
• a controller comprising a processor and a non-transitory computer readable medium that includes instructions which when executed by the processor are configured to cause the system to:
• capture, by the camera device, a first image of a surface, wherein the first image comprises presentation information that is disposed on at least a portion of the surface, and a portion of a presenter that is disposed between the camera device and the surface;
• perform a presenter segmentation process, comprising:
• detect the portion of the presenter in a second image that is derived from the first image, wherein the second image is a lower resolution version of the first image;
• and
• generate a presenter mask that is used to define pixels in the first image that are associated with the detected portion of the presenter;
• perform a canvas reconstruction process, comprising:
• replace the pixels in the first image that are associated with the detected portion of the presenter within the presenter mask to form a reconstructed canvas image;
• perform a presentation information segmentation process, comprising:
• generate a presentation information mask that includes pixels in the reconstructed canvas image that contain portions of the presentation information;
• and
• perform a background reconstruction process, comprising:
• reconstruct the pixels in the reconstructed canvas image that contain the portion of the presentation information to form a canvas background image.
