cvIntegral Method (image, sum, sqsum, tilted_sum)
NamespacesEmgu.CVCvInvokecvIntegral(IntPtr, IntPtr, IntPtr, IntPtr)

www.emgu.com/wiki
Calculates one or more integral images for the source image Using these integral images, one may calculate sum, mean, standard deviation over arbitrary up-right or rotated rectangular region of the image in a constant time. It makes possible to do a fast blurring or fast block correlation with variable window size etc. In case of multi-channel images sums for each channel are accumulated independently.

Parameters
image (IntPtr)
The source image, WxH, 8-bit or floating-point (32f or 64f) image.
sum (IntPtr)
The integral image, W+1xH+1, 32-bit integer or double precision floating-point (64f).
sqsum (IntPtr)
The integral image for squared pixel values, W+1xH+1, double precision floating-point (64f).
tilted_sum (IntPtr)
The integral for the image rotated by 45 degrees, W+1xH+1, the same data type as sum.
