Disparity map comparison. The RMSE values are shown below each disparity. First row: HDR reference disparity maps illustrated in Fig. 2. Reinhard, Fattl, and Durand TMOs achieve disparities with bigger error than conventional LDR stereo matching. Gastal, Drago, He, and Farbman TMOs perform better than LDR stereo matching while our combined graph-cut approach outperforms all of the LDR and tone-mapped disparity maps
