In the paper by Kim et al. (2003), the authors propose a new image scaling method called winscale. The presented method can be used for scaling up and down. However, scaling down utilizing the winscale concept gives exactly the same results as the well-known bilinear interpolation. Furthermore, compared to bilinear, scaling up with the proposed winscale "overlap stamping" method has very similar calculations. The basic winscale upscaling differs from the bilinear method.
