Goal & Information

Initial goal

We study the issue of quality assessment in tone mapping-based high-dynamic-range (HDR) image compression. In this, there aretwo stages at which a decision should be made regarding perceptual vis-ual quality : (a) for finding the optimal parameters of the dynamic rangereduction function so that the visual quality is maximized, and (b) visualquality judgment of the decompressed image. We first investigate twoobjective optimization criteria, namely mean squared error and structuralsimilarity index measure, toward optimization of a tone mapping model-based HDR image compression method. We then conduct a comprehen-sive subjective study to evaluate the visual quality of the compressed HDRimages.

Possible usage

You can use this database to evaluate the correlation between your quality models and subjective evaluation on HDR contents.
