Abstract

A method includes determining, at an image processing device, object quality values for a plurality of objects based on portions of image data corresponding to an image. Each portion corresponds to an object of the plurality of objects represented in the image. The method includes accessing, via the image processing device, object category metrics associated with an object category corresponding to each object of the plurality of objects. The method also includes determining, with the image processing device, image processing for the image based on comparisons of the object quality values for each object to corresponding object category metrics.

Claims

1. A method comprising:

determining, at an image processing device, object quality values for a plurality of objects based on portions of image data corresponding to an image, each portion corresponding to an object of the plurality of objects represented in the image;

accessing, via the image processing device, object category metrics associated with an object category corresponding to each object of the plurality of objects; and

determining, with the image processing device, image processing for the image based on comparisons of the object quality values for each object to corresponding object category metrics.

2. The method of claim 1, further comprising implementing the image processing to generate modified image data for the image.

3. The method of claim 2, further comprising sending the modified image data to a display device to display the image.

4. The method of claim 1, further comprising determining, based on the comparisons of the object quality values for each object to corresponding object category metrics, whether the image data has been altered.

5. The method of claim 4, further comprising sending a notification to a display device, wherein the notification indicates that the image data has been altered.

6. The method of claim 1, wherein an object category repository stores the object category metrics.

7. The method of claim 1, wherein the image comprises a frame of a video stream.

8. The method of claim 1, wherein the image processing includes modifying an image processing parameter of the image processing device.

9. The method of claim 8, wherein the image processing parameter includes an image resolution parameter, a frame rate parameter, an encoding parameter, a bandwidth parameter, a bitrate parameter, an image capture device mode parameter, or combinations thereof.

10. The method of claim 1, wherein the image processing for the image includes modifying values of the image data corresponding to a particular object.

11. A system comprising:

a processor; and

a memory accessible to the processor, the memory comprising instructions that, when executed by the processor, cause the processor to execute operations including;

determining object quality values for a plurality of objects based on portions of image data corresponding to an image, each portion corresponding to an object of the plurality of objects represented in the image;

accessing object category metrics associated with an object category corresponding to each object of the plurality of objects; and
