Paper Abstract

The perceptual linearization of video display monitors plays a significant role in medical image presentation. First, it allows the maximum transfer of information to the human observer. Second, for an image to be perceived as similarly as possible when seen on different displays, the two displays must be standardized. Third, perceptual linearization allows us to calculate the perceived dynamic range of the display device, which allows comparison of the maximum inherent contrast resolution of different devices. This paper provides insight into the process of perceptual linearization by decomposing it into the digital driving level to monitor luminance relationship, the monitor luminance to human brightness perception relationship, and the construction of a linearization function derived from these two relationships. We compare and contrast the results of previous work with recent experiments in our laboratory and related work in vision and computer science. Based on these analyses we give recommendations for using existing methods when appropriate, and propose new methods or suggest additional work where the current methods fall sort. Finally, we summarize the significant issues from all three component areas.
