High dynamic range tone mapping optimization on perceptual quality and processor specific efficiency

With the popularization of high dynamic range (HDR) devices, many tone mapping techniques have been proposed. By analyzing the relationship between the architecture of specific processors and path-wise retinex tone mapping technique, and by applying perceptual quality assessment of images collected from human observers, this paper proposes a novel path-wise retinex optimization method. A peculiar feature of this approach is the way its parameters can be adjusted to tradeoff its performance in speed and in perceptual quality. Experiments and results are presented and discussed.
