-Generate ​an integral image from input map.+Generates ​an integral image (summed-area table) ​from a map: each output cell holds the cumulative sum of all cells up to and including its position. See [[https://​en.wikipedia.org/​wiki/​Summed-area_table|Summed-area table]] for background on the technique.
