Updating an image

A computer-implemented method comprising:

• receiving, using the computer, an image that is shared between the computer and a second device, the image being divided into an array of contiguous sub-tiles, each sub-tile comprising at least one picture element of the image;
• displaying, using the computer, the image on a display associated with the computer;
• receiving, using the computer, at least a first encoded tile associated with an update to the image from the second device, the at least first encoded tile comprising one or more sub-tiles of the array of contiguous sub-tiles associated with changed sub-tiles of the image, wherein an efficiency algorithm is utilized to determine an optimal configuration of the at least first encoded tile and to vary the number of sub-tiles within the at least first encoded tile, based on the optimal configuration, such that the tile includes at least one sub-tile with changed content of the image and at least one sub-tile containing unchanged content of the image;
• decoding, using the computer, the at least first encoded tile effective to generate a respective decoded tile;
• and
• updating, using the computer, the displayed image based, at least in part, on the respective decoded tile.

A system comprising:

• one or more processors;
• and
• one or more memories comprising instructions stored thereon that, responsive to execution by the one or more processors, are configured to:
• display, with a first device, a received image that is shared to the first device from a second device which displays the image, the received image being divided into an array of contiguous sub-tiles, each sub-tile comprising at least one picture element of the received image;
• receive, with the first device, at least a first encoded tile associated with an update to the received image from the second device, the at least first encoded tile comprising one or more sub-tiles of the array of contiguous sub-tiles that are changed sub-tiles of the received image, the configuration of the at least first encoded tile being flexible to enable a variety number of sub-tiles within the at least first encoded tile, the one or more sub-tiles of the array of contiguous sub-tiles comprising:
• at least one sub-tile with changed content of the image;
• and
• at least one sub-tile containing unchanged content of the image;
• decode, with the first device, the at least first encoded tile effective to generate a respective decoded tile;
• and
• update, with the first device, the displayed received image based, at least in part, on the respective decoded tile,
• wherein the at least a first encoded tile associated with an update is based, at least in part, on assigned respective weights to the changed sub-tiles of the image, wherein the assigned respective weights are used in one of a clustering technique or a dimension reduction technique to determine a configuration associated with the at least first encoded tile.
