An improved HDRI acquisition algorithm based on quality measurement

In order to reduce the gap between dynamic range of real scene and that of traditional imaging devices, a high dynamic range (HDR) image acquisition algorithm based on quality measurement is proposed. The algorithm fuses a stack of multi-exposure image sequence in image domain. The weighting map of an image is determined by a quality measurement, and then further smoothed in order to reduce possible blocking artifact. Experiments show that the proposed algorithm provides an HDR image with rich details. Moreover, the HDR image acquired can be clearly shown on low dynamic range displaying device without tone-mapping work and save the complexity computation.
