3. The computing device of claim 1 , wherein the computer-executable instructions causing the computing device to perform the identifying, the selecting, and the determining, are part of a first classifier that generates a first classifier output identifying a first set of portions of the image as depicting physical objects of the first predefined type; and wherein further the computer-readable media comprise further computer-executable instructions, which, when executed by the one or more processing units, cause the computing device to: assign a first weight to the first classifier output to generate a weighted first classifier output; receive, from a second classifier, a second classifier output that identifies a second set of portions of the image as depicting physical objects of the first predefined type; assign a second weight to the second classifier output to generate a weighted second classifier output; and amalgamate the weighted first classifier output with the weighted second classifier output; wherein the automatically identifying the portions of the image of the physical scene as depicting the physical objects of the predefined types is based on the amalgamating.
