ABSTRACT:
A method and apparatus are described for providing a scaled expanded image array of an original image array representing a physical entity, such as an image or sequence of frames, by utilizing fractal transform methods. The method of the invention includes steps performed by a data processor. Fractal transform methods are used to select a best domain/range block correspondence in an original image array. The range block is larger than the domain block. A subset of the data values in the range block is selected. Finally, an area of the expanded image array is populated with the data values in the selected subset where the area corresponds to the domain block location in the original image array.
