SqrIntegral
Given an input image and the specified value , the pixel value of the integral image at coordinate (i, j) will be computed as $pDst(j,i) = nVal + \sum_{l=0}^{j-1}\sum_{k=0}^{i-1}pSrc(l,k)$ Given an input image and the specified value , the pixel value of the squared integral image at coordinate (i, j) will be computed as $pSqr(j,i) = nValSqr + \sum_{l=0}^{j-1}\sum_{k=0}^{i-1}{pSrc(l,k)}^2$ If the size of the input image is $W \times H$ , the size of the squared integral image will be $(W+1) \times (H+1)$ .
