Abstract: A system and method are provided for measuring image quality using an ambient adaptive objective brightness metric. The method accepts an electronically formatted original image (I), and also accepts an electronically formatted brightened image (B), obtained by modifying the original image. For example, the brightened image (B) may be an illumination-modified original image. The method also accepts a relative ambient illumination value (?). A dynamic reference AI=I? is generated, and the brightened image (B) is compared to the dynamic reference (AI).

Abstract: A method is provided for efficiently managing energy consumption using stored energy. The method accepts input energy (e.g., from a power utility) and maintains a record of energy consumption. An energy consumption peak is predicted in response to analyzing the record of energy consumption, and the input energy is augmented with stored energy during the predicted energy consumption peaks. More explicitly, a peak shaving value is selected based on a fraction of the predicted energy consumption peak, and the stored energy is used when energy consumption exceeds the peak shaving value. In one aspect, after a determination is made to use stored energy, it is simply used while it is available. Otherwise, it is supplied based upon an analysis of a predicted value of the stored energy.
