Tone-mapping operators (TMOs) that convert high dynamic range (HDR) to low dynamic range (LDR) images, so as to visualize HDR images on standard displays. Different TMOs create different tone-mapped images and a natural question is which one has the best quality. this paper introduces a fusion technique based on wavelet transforms that combines the output of several operators in a single image, based on objective quality maps that do not depend on the dynamic range of neither the input nor the
