I would like to calculate the integral image of a given source image. I found the function NppStatus nppiSqrIntegral_8u32s32f_C1R(Npp8u pSrc, int nSrcStep, Npp32s pDst, int nDst-
Step, Npp32f pSqr, int nSqrStep, NppiSize srcROI, Npp32s val, Npp32f valSqr, Npp32s integral-
ImageNewHeight) in the NPP library.
In the documentation (http://developer.download.nvidia.com/compute/cuda/4_0_rc2/toolkit/docs/NPP_Library.pdf) it says the integral image and square integral image will be calculated.
Is it possible to only calculate the integral image?
