Abstract
A method, apparatus and computer program product are disclosed to provide improved temporal stabilization of a control algorithm associated with the processing of streaming frames. In the context of a method, the number of immediately preceding consecutive frames during which a filtered value has been greater than a current value of the current frame is determined or the number of immediately preceding, consecutive frames during which the filtered value has been less than the current value of the current frame is determined. The method also includes determining a weight based upon the number of immediately preceding, consecutive frames. The weight is configured to vary in a direct relationship to the number of immediately preceding, consecutive frames. The method also determines a filtered value of a current frame based upon a combination of the weight and the difference between the prior filtered value and the value of the current frame.
