Abstract
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 determines an angle of orientation of the sample values. Kernel values for each of the discrete sample values are then calculated using one of a plurality of first kernels, depending upon the angle of orientation of the discrete sample value. The first kernels are constructed by rotating a second kernel from a first angle of orientation to a second angle of orientation. Finally, the kernel values are convolved with the discrete sample values to provide a representation of said image data.
