摘要： Embodiments of the present invention disclose techniques for outputting content aware video based on at least one a video application use case. The technique recognizes objects associated with the use case and performs enhancement of the objects based on content-aware rules, and composes at least some of the objects in an output frame based on on content-aware frame composition templates. Embodiments of the present invention also disclose systems for implementing the above techniques.

摘要： For video applications, a method for dynamically switching from a current ROI to a target ROI is disclosed, wherein the target ROI only includes active speakers. Advantageously, if the target ROI crops a non-speaker, then the target ROI is expanded to include said non-speaker. Transitioning from the current ROI to the target ROI may be achieved based on a cutover transition technique, or a smooth transition technique. The cutover transition technique achieves the change from the current arrived to the target ROI in a single interval, whereas the smooth transition technique achieves the change over a number of intervals, wherein a percentage of the total change required is allocated to each interval. A system for implementing the above method is also disclosed.
