Objective quality assessment of lossy image compression codecs have become an important part of the recent call of the JPEG committee for Advanced Image Coding. The aim of this work is twofold: First, we present state-of-the-art still image codecs, JPEG [1] in two variations, a visual and PSNR optimal JPEG2000 [2, 3] version, H.264/AVC [4, 5] and the recently proposed HDPhoto format [6, 7] introduced by Microsoft. We measure the performance of these codecs by subjective, full-reference ordering tests and two visual image quality metrics on a carefully selected test set. Second, we evaluate the prediction quality of the metrics by comparing them with the outcome of the subjective tests.

More about this publication?
  • Started in 2002 and merged with the Color and Imaging Conference (CIC) in 2014, CGIV covered a wide range of topics related to colour and visual information, including color science, computational color, color in computer graphics, color reproduction, volor vision/psychophysics, color image quality, color image processing, and multispectral color science. Drawing papers from researchers, scientists, and engineers worldwide, DGIV offered attendees a unique experience to share with colleagues in industry and academic, and on national and international standards committees. Held every year in Europe, DGIV papers were more academic in their focus and had high student participation rates.
