METHOD AND DEVICE FOR SELECTING AN IMAGE DYNAMIC RANGE CONVERSION OPERATOR

摘要

The invention relates to a method for selecting an image dynamic range conversion operator from among a set of image dynamic range conversion operators by optimising a quality criterion, each image dynamic range conversion operator being applied to an original image to obtain an image, called the modified image, whose dynamic range is lower than that of the original image, wherein said quality criterion is calculated, for each image dynamic range conversion operator, as a function of a distortion calculated from a reconstructed version after coding and decoding the original image modified by said image dynamic range conversion operator.
