First Claim
Patent Images

1. A method of applying a blur to an image using a processor to perform the steps of:

  • defining a primary kernel to compute an output pixel as a weighted average of a plurality of pixels of the image wherein a spatial relationship between the output pixel and the plurality of pixels is determined by a step size of the primary kernel;

    applying the primary kernel to each pixel of the image to produce an intermediate result;

    increasing the step size of the primary kernel to create a higher order primary kernel and applying the higher order primary kernel to the intermediate result to produce a result image.
