Abstract: PURPOSE: A quality measuring system of several class images and system thereof are provided to evaluate the image quality of multiple layers based on a quality measuring result of each layer. CONSTITUTION: A bitstream extraction unit(110) separates an inputted multi-level image into a base layer bitstream and an enhanced layer bitstream. A base layer quality measuring unit(120) generates image quality measuring result information of a base layer image. An enhanced layer quality measuring unit(130) generates image quality measuring result information. An integrated quality evaluation unit(140) evaluates the effective quality of the several class images.
