Abstract
Gaze tracking data representing a viewer's gaze with respect to one or more images presented to the viewer is used to generate foveated image data representing one or more foveated images characterized by a higher level of detail within one or more regions of interest and a lower level of detail outside the regions of interest. The image data for portions outside the one or more regions of interest is selectively filtered to reduce visual artifacts due to contrast resulting from the lower level of detail before compositing foveated images for presentation.
Claims13
A graphics processing method comprising:
- obtaining gaze tracking data representing a viewer's gaze with respect to one or more images presented to the viewer;
- generating foveated image data representing one or more foveated images using the gaze tracking data, wherein the one or more foveated images are generated with a higher level of detail within one or more regions of interest than a lower level of detail for one or more portions of the foveated images outside the one or more regions of interest;
- filtering the image data for the at least the one or more portions of the foveated images outside the one or more regions of interest to reduce visual artifacts due to contrast resulting from the lower level of detail;
- and
- compositing the one or more filtered foveated images;
- and
- displaying the one or more filtered foveated images to the viewer on a display device.
A system, comprising:
- a processor;
- a memory;
- and
- computer-readable instructions embodied in the memory, the computer-readable instructions being configured to implement a graphics processing method when executed, the graphics processing method comprising:
- obtaining gaze tracking data representing a viewer's gaze with respect to one or more images presented to the viewer;
- generating image data representing one or more foveated images using the gaze tracking data, wherein the one or more foveated images are generated with a higher level of detail within one or more regions of interest than a lower level of detail for one or more portions of the foveated images outside the one or more regions of interest;
- generating filtered image data by filtering the image data for the at least the one or more portions of the foveated images outside the one or more regions of interest to reduce visual artifacts due to contrast resulting from the lower level of detail;
- and
- displaying a final composited image comprised of one or more filtered foveated images to the viewer on a display device.
A non-transitory computer-readable medium having computer-readable instructions embodied therein, the computer-readable instructions being configured to implement a graphics processing method when executed, the graphics processing method comprising:
- obtaining gaze tracking data representing a viewer's gaze with respect to one or more images presented to the viewer;
- generating image data representing one or more foveated images using the gaze tracking data, wherein the one or more foveated images are generated with a higher level of detail within one or more regions of interest than a lower level of detail for one or more portions of the foveated images outside the one or more regions of interest;
- generating filtered image data by filtering the image data for the at least the one or more portions of the foveated images outside the one or more regions of interest to reduce visual artifacts due to contrast resulting from the lower level of detail;
- and
- displaying a final composited image comprised of one or more filtered foveated images to the viewer on a display device.
