A method of providing a representation of image data is disclosed. The method accesses a plurality of discrete sample values of the image data and calculates kernel values for each of the discrete sample values using a scaled kernel. The scaled kernel is constructed by transforming a kernel from a first range to a second range. In order to provide a representation of the image data, the kernel values are convolved with the discrete sample values.
