Required quantizing resolution for perceptually linearized medical x-ray images on display monitor
This paper theoretically clarifies required quantizing resolution to display digitized x‐ray images on a cathode‐ray‐tube (CRT) monitor provided that the observer not recognize contours that do not exist in original x‐ray film images. Human visual system for luminance difference discrimination is an...

| description | This paper theoretically clarifies required quantizing resolution to display digitized x‐ray images on a cathode‐ray‐tube (CRT) monitor provided that the observer not recognize contours that do not exist in original x‐ray film images. Human visual system for luminance difference discrimination is an important factor in determining required quantizing resolution. We therefore carry out an analysis using the Barten model, which provides good fit of many experimental data. First, we clarify the required quantizing resolution for the density input to film and that for the voltage input to a CRT monitor. Then, we present the design results of the look‐up table for perceptually linear transform for a CRT that can reproduce the luminance difference information in film images, and clarify the validity of our theoretical studies. © 2003 Wiley Periodicals, Inc.
