3. The method of claim 1 , wherein the one or more perceptual enhancement operations comprise one or more of: maintaining skin tone of a character represented by the salient object, maintaining a spatial resolution of the salient object in image rendering, performing no or little compression of image data of the salient object, increasing local contrast of the salient object, increasing brightness or luminance of the salient object, increasing color saturation of the salient object, amplify optically a salient, creating a viewport around the salient object, implementing specific temporal behaviors of image rendering of the salient object, pulsating one or more local visual adjustments applied to the salient object, or flashing a visible attribute of the salient object, relative to other visual features not represented by the salient object.
1. A method, comprising: collecting image data relating to one or more real-world objects or persons from a scene while collecting audio data relating to the one or more real-world objects or persons from the same scene, the audio data being used to derive one or more sound objects corresponding to the one or more real-world objects or persons, the image data being used to derive one or more video objects corresponding to the one or more real-world objects or persons; generating, based on the one or more sound objects and the one or more video objects, one or more candidate salient objects; selecting a salient object from among the one or more candidate salient objects and performing one or more perceptual enhancement operations on the salient object; wherein the method is performed by one or more computing devices.
