: Apply the Averaging Filter to an image   For this task you will be implementing the averaging filter algorithm

  used in Digital Image Processing. You will be given a pointer to the

  source image (2D array of type unsigned char) along with the number

  of rows an columns in that image. You will be also given a pointer to

  the destination image. Your algorithm will scan the source image element

  by element (or pixel by pixel) and compute the average of all the neighbors

  of that pixel. This average value will be assigned to the corresponding

  pixel in the destination image.
