I am not sure about Joe's comment, I don't need it to THAT amount of details. MATLAB provides its own laplacian in the image toolbox: "impyramid(image,'reduce')".

However, the one provided in the image toolbox is not an invertible operation (you cannot obtain the original image by an update and then a reduce, as the sizes of these output matrices don't match... making that implementation useless....

Good stuff.

But I can't understand why you pad two rows/columns in 'REDUCE' but only pad one row/column for 'EXPAND'
