1. Apparatus for processing a plurality of input signals comprising:
- a perceptual metric generator for determining a perceptual metric that represents the fidelity between two of said input signals; and
a first neural network, coupled to said perceptual metric generator, for evaluating said perceptual metric to produce a control signal.

Abstract
A signal processing apparatus and concomitant method for learning and using fidelity metric as a control mechanism and to process large quantities of fidelity metrics from a visual discrimination measure (VDM) to a manageable subjective image quality ratings. The signal processing apparatus incorporates a VDM and a neural network. The VDM receives input image sequences and generates fidelity metrics, which are received by a neural network. The neural network is trained to learn and use the fidelity metrics as a control mechanism, e.g., to control a video encoder.
