    % Note that the aspect ratio is not preserved. In Caltech 101, the
    % object of interest is centered in the image and occupies a
    % majority of the image scene. Therefore, preserving the aspect
    % ratio is not critical. However, for other data sets, it may prove
    % beneficial to preserve the aspect ratio of the original image
    % when resizing.
