Abstract
A classified adaptive spatio-temporal creation process is utilized to translate data from one format to another. This process creates new pixels by applying a filter selected on an output pixel by pixel basis which has been adaptively chosen from an application-specific set of three-dimensional filters. In one embodiment, a standard orientation is chosen, which is defined according to each output data position. Input data is flipped to align the output data position with the output position of the standard orientation. A classification is performed using the flipped input data and an appropriate filter is selected according to the classification. The filter is then executed to generate the value of the output data point.
