Effect of Image Sharpening on Radiographic Image Quality
… and processing of the digital radiographic images may contain artifacts that could reduce the diagnostic value of dental radiographs. This phenomenon has been reported through various case reports. However, its effect on radiographic image quality has not been studied. The purpose of this …

Automated image sharpening via supervised learning with human preferences
We propose an automatic method for image sharpening that maximizes the perceptual sharpness while preserving naturalness and original colors of a given image. We hypothesize a set of image properties to model the context for selection of sharpening parameters. We hypothesize and then verify that …

Preferred levels of image sharpness and their relation to image structure in thermal dye transfer prints
… research were (1) to develop scales of preferred image sharpness for thermal dye transfer prints and (2) to relate these scales to an objective measurement of image quality. Interval scales were developed using two different indirect scaling techniques, paired comparison and rank ordering, for …
