Fig. 5From: Two dimensional smoothing via an optimised Whittaker smootherSmoothing a two dimensional histogram: Added some noise to mammography. [Upper left graph:] A breast mammography. An area that seems like a tumour has been marked with a cross. [Upper right graph:] obscured by Gaussian noise, [Lower left graph:] smoothed by kernel smoother [Lower right graph:] smoothed by Whittaker smoother with optimisationBack to article page
