Abstract
Various embodiments of this disclosure may describe apparatuses, methods, and systems including an encoding engine to encode and/or compress one or more objects of interest within individual image frames with higher bit densities than the bit density employed to encode and/or compress their background. The image processing system may further include a context engine to identify a region of interest including at least a part of the one or more objects of interest, and scale the region of interest within individual image frames to emphasize the objects of interest. Other embodiments may also be disclosed or claimed.
Claims18
An apparatus comprising:
- a context engine to:
- receive a plurality of image frames of a video signal;
- analyze the respective image frames;
- identify, based upon the analysis of the respective image frames, a plurality of objects of interest within the respective image frames;
- and
- identify, based on the plurality of objects of interest, a plurality of regions of interest within the respective image frames;
- an encoding engine coupled to the context engine, the encoding engine to:
- adjust, based on a context information, size, position, or scaling of the region of interest to re-center the region of interest within the respective image frames, wherein the context information includes a detection of one or more changes from one or more previous image frames of one of the plurality of objects of interest;
- and
- encode the region associated with the plurality of objects of interest within respective image frames based on one or more bit densities that are higher than a bit density of a background region, wherein the background region surrounds the region associated with the plurality of objects of interest;
- and
- a transmitter coupled to the encoding engine, the transmitter to transmit the encoded plurality of image frames to one or more recipients.
