Abstract
A numerical observer (JPEGNO) to evaluate the influence of JPEG compression on the diagnostic quality of CT image is proposed. JPEGNO is based on the grey scale histogram of the image and is defined as the inverse of the sum of the difference between successive grey levels in the histogram of the image.
