A Nonlinear, Image-content Dependent Measure of Image Quality
Linköping University, Department of Electrical Engineering. Linköping University, The Institute of Technology.
1977 (English)Report (Other academic)
Abstract [en]

In recent years, considerable research effort has been devoted to the development of useful descriptors for image quality. The attempts have been hampered by i n complete understanding of the operation of the human visual system. This has made it difficult to relate physical measures and perceptual traits.

A new model for determination of image quality is proposed. Its main feature is that it tries to invoke image content into consideration. The model builds upon a theory of image linearization, which means that the information in an image can well enough be represented using linear segments or structures within local spatial regions and frequency ranges. This implies a l so a suggestion that information in an image has to do with one- dimensional correlations. This gives a possibility to separate image content from noise in images, and measure them both.

Also a hypothesis is proposed that the visual system of humans does in fact perform such a linearization.
