Abstract
A pixel value estimation technique uses non-linear prediction to estimate a pixel value before the pixel is known, based on previous values seen. Initially, a number of classes are defined. Each class is a template for a pattern of pixel values. The pixels constituting the support for the prediction of a given pixel are compared to each template. A value giving the goodness of fit to each template is determined as well as a predicted pixel value based on that template. The predictions from each template are averaged together using weights related to the goodness of the fit to that template to produce a consolidated prediction.
