Abstract
Example methods, apparatuses, and/or articles of manufacture are disclosed that may be implemented, in whole or in part, techniques to apply an image anti-aliasing operation to an image frame. In a particular implementation, an anti-flicker process may be applied to a portion of an image frame based, at least in part, on a rate of change in an intensity in the image frame.
Claims20
A computer-implemented method comprising:
- receiving a temporal sequence of time instances, each time instance comprising one or more samples;
- and
- for a current time instance in the temporal sequence of time instances:
- computing a signal that is indicative of a rate of change in at least one value of one or more samples of the current time instance;
- generating an accumulated difference value based on the computed signal and an accumulated difference value generated for a previous time instance in the temporal sequence of time instances;
- and
- applying the accumulated difference value to correct at least one value of one or more samples in a selected time instance of the temporal sequence of time instances or an operation to be applied to the at least one value of one or more samples in the selected time instance of the temporal sequence of time instances.

A computing device comprising:
- one or more memory devices;
- and
- one or more processors coupled to the one or more memory devices to:
- obtain a temporal sequence of time instances, each time instance comprising one or more samples;
- and
- for a current time instance in the temporal sequence of time instances:
- compute a signal to be indicative of a rate of change in at least one value of one or more samples of the current time instance;
- and
- generate an accumulated difference value based on the computed signal and an accumulated difference value generated for a previous time instance in the temporal sequence of time instances;
- and
- apply the accumulated difference value to correct at least one value of one or more samples in a selected time instance of the temporal sequence of time instances or an operation to be applied to the at least one value of the one or more samples in the selected time instance of the temporal sequence of time instances.

An article comprising:
- a non-transitory storage medium comprising computer-readable instructions stored thereon, the computer-readable instructions to be executable by one or more processors to:
- obtain a temporal sequence of time instances, each time instance comprising one or more samples;
- and
- for a current time instance in the temporal sequence of time instances:
- compute a signal to be indicative of a rate of change in at least one value of one or more samples of the current time instance in the at least one value;
- and generate an accumulated difference value based on the computed signal and an accumulated difference value generated for a previous time instance in the temporal sequence of time instances;
- and
- apply the accumulated difference value to correct at least one value of one or more samples in a selected time instance of the temporal sequence of time instances or an operation to be applied to the at least one value of the one or more samples in the selected time instance of the temporal sequence of time instances.
