An experiment was conducted for subjective assessment of sharpness and colour preference for images displayed on a CRT monitor screen. Blurred versions of each of four original images were generated by convolution with a low-pass Gaussian filter. Sharpened versions of these images were created through adjustment of the image power spectrum. The perceived sharpness results showed a good correlation with the preferred image colour. The SQRI image quality metric was investigated for applicability to the observer results.

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.
