Integral

Given an input image $pSrc$ and the specified value $nVal$, the pixel value of the integral image $pDst$ at coordinate (i, j) will be computed as

\[pDst(j,i) = nVal + \sum_{l=0}^{j-1}\sum_{k=0}^{i-1}pSrc(l,k)\]

If the size of the input image is $W \times H$, the size of the integral image will be $(W+1) \times (H+1)$.
