Calculates the integral of an image.
- image_in – Input image as W x H, 8-bit or floating-point (32f or 64f).
- sdepth_in – Desired depth of the integral and the tilted integral images, CV_32S, CV_32F, or CV_64F.
- sum_out – Integral image as (W+1) x (H+1) , 32-bit integer or floating-point (32f or 64f).
