Minimizing Veiling Glare in the High-Luminance-Range Visualization of Medical Images

摘要

We propose a method to adjust the luminance mapping of medical images on high-dynamic-range (HDR) display devices that minimizes perceptual and hardware veiling glare effects. We utilize the DICOM grayscale standard display function to compute the maximum number of just-noticeable-differences (JND) for an HDR prototype (dual-layer LCD). Using previous findings, a unique image will be displayed with a front and back LCD panel such that the combined light modulation produces the most accurate luminance representation of the image and the least hardware glare. Next, we use an empirical, image-dependent model to analyze regions of interest in the image that may suffer from perceptual veiling glare and adjust the luminance mapping until a reasonable degradation tolerance for detection thresholds is reached.
