procedure integral(sum: TIEVisionImage; sqsum: TIEVisionImage; tilted_sum: TIEVisionImage); overload; safecall;

#### Description

Calculates the integral of an image.

Parameter | Description |

sum | Integral image as (W + 1) x (H + 1) , 32-bit integer or floating-point (32f or 64f). |

sqsum | Integral image for squared pixel values. It is (W + 1) x (H + 1), double-precision floating-point (64f) image (matrix). |

tilted_sum | Integral for the image rotated by 45 degrees. It is (W + 1) x (H + 1) image (matrix) with the same data type as sum. |
