Abstract:A technique for assessing the impact of lossy wavelet-based image compression on signal detection tasks is presented. A medical image's value is based on its ability to support clinical decisions, including detecting and diagnosing abnormalities. However, image quality of compressed images is often stated in terms of mathematical metrics such as mean square error. The presented technique provides a more suitable measure of image degradation by building on the channelized Hotelling observer model, which has bee… Show more
