Different PB-PCA projections: a comparison between PSNR of the different methods of the projections in PB-PCA for the House and Cameraman images. The threshold ratio (λ/σ) into the bottom of x-axis controls the number of axes kept in the upper x-axis. σ is the noise variation, and λ is chosen by cross validation [13]
