The documentation for PyrUp says:
"This function up-samples the source image pSrc, that is, inserts odd zero rows and columns, and then applies the 5x5 Gaussian multiplied by 4 to it."
Does using PyrUp on pSrc result in an output image pDst with dimensions (widthSrc*2+1, heightSrc*2+1), (widthSrc*2, heightSrc*2), or (widthSrc*2-1, heightSrc*2-1)? That is, does PyrUp only insert "internal" rows and columns, does it insert rows and columns on one side, or does it insert columns on both sides?
