Consider the following "image":

(a) Obtain the two-dimensional DWHT transform by first taking the one-dimensional transform of the rows, then taking the column-by-column transform of the resulting matrix.
(b) Obtain the two-dimensional DWHT transform by first taking the one-dimensional transform of the columns, then taking the row-by-row transform of the resulting matrix.
(c) Compare and comment on the results of (a) and (b).
