Abstract

To visualize high dynamic range (HDR) images on common low dynamic range (LDR) displays, some tone-mapping operators (TMOs) are proposed in previous studies. TMOs convert specific HDR image to various LDR images, thus the quality assessment of these tone-mapped images or TMOs become a natural question. In this work, an objective quality index named color difference matrix index (CDMI) is proposed. It compares the CIEDE2000 color difference matrix between the HDR image and LDR images, thus the color information, which is ignored by many previous methods, is involved. CDMI is then compared and combined with other methods: TMQI and FSITM later in experiments. It is shown that CDMI have edges over other index in many aspects and have a satisfying result when combined with these two indices.
