Claim 21:
22. A computer system comprising:
a processor; and
a memory storing software instructions that, when executed by the processor, cause computation of quality metrics for automatic exposure (AE) control, the software instructions comprising software instructions to:
receive parameters in a weight learning component coupled to a virtual imaging system, the parameters comprising a range of candidate weight values, a set of starting exposure values (EVs), and a number of time steps n of an iterative operation;
perform the iterative operation on the virtual imaging system for a plurality of scenes stored in a scene database coupled to the virtual imaging system using differing combinations of candidate sets of weight values selected from the range of candidate weight values and starting EVs selected from the set of starting EVs, wherein an individual step of the iterative operation comprises computing n EVs for a scene using a candidate set of weight values and a starting EV, wherein the scene comprises a plurality of images; and
compute, by the weight learning component, quality metrics for each candidate set of weight values based on the n EVs computed during each step of the iterative operation performed using the candidate set of weight values.
