Blur an Image Using an Average Filter

Read and display the input image.

   I = imread('pout.tif');

Compute the integral image.

   intImage = integralImage(I);

Apply a 7-by-7 average filter.

   avgH = integralKernel([1 1 7 7], 1/49);
   J = integralFilter(intImage, avgH);

Cast the result back to the same class as the input image.

   J = uint8(J);
