  • Publication number: 20210311307
    Abstract: A method includes obtaining, from a memory of an electronic device connected to a head mounted display (HMD), a first reference frame, wherein the first reference frame comprises a first set of pixels associated with a first time. The method includes, rendering, at the electronic device, a source image as a new frame, wherein the new frame includes a second set of pixels associated with a display to be provided by the HMD at a second time, and generating, by the electronic device, a differential frame, wherein the differential frame is based on a difference operation between pixels of the new frame with pixels of the first reference frame to identify pixels unique to the new frame. Still further, the method includes sending the differential frame to the HMD, and storing the new frame in the memory of the electronic device as a second reference frame.

  • Patent number: 10902262
    Abstract: One embodiment provides a method comprising classifying one or more objects present in an input comprising visual data by executing a first set of models associated with a domain on the input. Each model corresponds to an object category. Each model is trained to generate a visual classifier result relating to a corresponding object category in the input with an associated confidence value indicative of accuracy of the visual classifier result. The method further comprises aggregating a first set of visual classifier results based on confidence value associated with each visual classifier result of each model of the first set of models. At least one other model is selectable for execution on the input based on the aggregated first set of visual classifier results for additional classification of the objects. One or more visual classifier results are returned to an application running on an electronic device for display.
