Objective Fidelity Metrics

The objective fidelity metrics category contains the functions that calculate error metrics, including root-mean-square (rms) error, signal-to-noise ratio (snr) and peak snr. The metrics are used for image comparison and will provide a mathematical based measure of similarity between two images. These are most useful for comparing similar versions of the same image, such as images that have been restored or compressed, and can be compared to the original.
