Refined Measurement of Digital Image Texture Loss / Noise-power spectrum

Posted presentation from the recent Electronic Imaging Symposium. This may be of interest to those developing imaging performance methods via (noise- or signal-) spectra. I describe a simple step that improves the power-spectrum measurement, by making it more robust in the presence lens shading, etc.
