Abstract

This paper describes the use of a simple model of visual importance in digital images, based on the use of contrast statistics for prediction of areas of detail which influence observer attention, to allow image compression to be undertaken at varying quality within an individual image. The effects of this strategy on expert observer perception of the reconstructed images, based on subjective image quality judgment and analysis of eye-position patterns, are considered by applying the model to sample mammograms, cervical and thoracic X-rays. The results indicate that consistent observer performance can be attained with images compressed in this way, at compression rates in excess of those reported for uniformly compressed images.
