Image quality assessments have shown that both JPEG and JPEG2000 compression schemes are dependent on scene content. This paper addresses the problem of scene dependency and scene susceptibility in image quality assessments and proposes image analysis as a means to group test scenes, according to basic inherent scene properties that human observers refer to when they judge the quality of images. Experimental work is carried out to investigate the relationship between scene content and the subjective results obtained from experimental work carried out in [S. Triantaphillidou, E. Allen, and R. E. Jacobson, “Image quality comparison between JPEG and JPEG2000. II. Scene dependency, scene analysis, and classification”, J. Imaging Sci. Technol. 51, 259 (2007)]. © 2007 Society for Imaging Science and Technology. The content of the test images used in this work is analyzed using simple image analysis measures that quantify various image features, such as original scene contrast and global brightness, amount of dominant lines, scene busyness (defined here as a scene/image property indicating the presence or absence of detail), and flat areas within the scene. Preliminary results and conclusions are obtained and suggestions are made to form a basis for further studies on scene dependency and scene classification with respect to image quality measurements.

More about this publication?
  • The Journal of Imaging Science and Technology (JIST) is dedicated to the advancement of imaging science knowledge, the practical applications of such knowledge, and how imaging science relates to other fields of study. The pages of this journal are open to reports of new theoretical or experimental results, and to comprehensive reviews. Only original manuscripts that have not been previously published, nor currently submitted for publication elsewhere, should be submitted.

    IS&T's JIST-first publication option allows authors wishing to present their work at conferences, but have a journal citation for their paper, to submit a paper to JIST that follows the same rigorous peer-review vetting and publication process as traditional JIST articles, but with the benefit of a condensed time-to-publication time frame and guaranteed conference presentation slot.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
