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.
