Paper Abstract
The subjective image quality is an important issue in all multimedia imaging systems with a significant impact onto QoS
(Quality of Service). For long time the image fidelity criterion was widely applied in technical systems esp. in both
television and image source compression fields but the optimization of subjective perception quality and fidelity
approach (such as the minimum of MSE) are very different. The paper presents an experimental testing of three different
digital techniques for the subjective image quality enhancement - color saturation, edge enhancement, denoising
operators and noise addition - well known from both the digital photography and video. The evaluation has been done
for extensive operator parameterization and the results are summarized and discussed. It has been demonstrated that
there are relevant types of image corrections improving to some extent the subjective perception of the image. The above
mentioned techniques have been tested for five image tests with significantly different image characteristics (fine details,
large saturated color areas, high color contrast, easy-to-remember colors etc.). The experimental results show the way to
optimized use of image enhancing operators. Finally the concept of impressiveness as a new possible expression of
subjective quality improvement is presented and discussed.
