Original Abstract Submitted
a method and apparatus for estimating a perceptual quality of a high dynamic range (hdr) image includes dividing an image into at least one static region and at least one dynamic region, weighting at least one artifact in the at least one static region and the at least one dynamic region through a visual saliency map, computing at least one edge preservation score based on a static hdr quality index (sqi), a dynamic hdr quality index (dqi) and the at least one weighted artifact, generating an output hdr quality metric by modulating the at least one computed edge preservation score on an input hdr quality metric, and estimating the perceptual quality of the hdr image based on the generated output hdr quality metric.
