Abstract :
In this paper, a method for measuring the perceptual image quality of JPEG-2000 coded images has been proposed. The image quality is characterized by the average edge-spread in the image, or more specifically the average extent of the slope´s spread of an edge in the opposing gradients´ directions. The proposed method is, in effect, a way of measuring the amount of blurring in the image. The effectiveness of such method is validated using subjective tests and the experimental results show that the proposed method can provide results that correlate relatively well with human subjective ratings.
