  • Title: Image Quality and Viewer Perception
    Writing Type: Paper
    Exhibition: SIGGRAPH 1990: Digital Image-Digital Cinema
    Abstract Summary:

    Improving the quality of digital images can have great impact on information storage and transfer, pushing the feasibility of image databases well beyond existing practical limits. How good do images have to be? Among the considerations for selecting image quality is the extent to which viewers can discriminate among variations in quality. What differences in resolution and dynamic range (bit-depth) can they see? Groups of art historians were asked to rate a series of displayed test images; the results show how participants’ responses compared with the actual range of image quality. Practical implications of viewers’ perceptions are discussed.
