Paper Abstract

The subjective image quality seems to be one of crucial parameters in modern multimedia systems. The perception of observer is a final issue to be followed and technical parameters of the system are the issues of second order. Therefore the traditional approach of "fidelity" would be better consequently replaced by the multimedia term the subjective image perceived quality or "goodliness". It can be shown that some distortions and/or artifacts can be perceived as pleasant and the goodliness will be increased when the distortion level is increased. At the same time the fidelity will drop down. Based upon more than four years of research experience the paper discusses various impacts of modem multimedia technology on the subjective quality of image. The main attention is focused on the image compression techniques and standards. The nature of distortions and artifacts is demonstrated on selected examples of image compression standards (fractals, DIVX, VP6 etc.). Finally the relevant image quality parameters are listed and analyzed for the area of imaging security systems.
