Abstract

In this evaluation contrast-detail diagrams were used to measure the effects on observer performance of several image processing algorithms such as edge enhancement, smoothing and histogram equalization. The observer task was the detection of disk images in a uniform background. A new digital system, DigiRad System One, was used to digitize and postprocess images of a "Rose-Burger" contrast phantom. Results show that detectability of low contrast objects may increase for images taken with standard film/screen combinations. Anticipated changes on the System One may enhance its capabilities significantly.
