Edge features within an image may be present at many scales, therefore application of edge detectors at multiple scales improves the accuracy of the detected edges. However, the computational complexity of application of the edge detection filter increases as the size of the filter increases. Using the finite element method in conjunction with integral images weillustrate a method of efficiently applying edge detection operators over an image at varying scales.
