Abstract

High dynamic range (HDR) images are rendered through base-detail separations. The representative detail preserved algorithm iCAM06 has a tendency to reduce the sharpness of dim surround images, because of the discrete calculation of the fast-bilateral filter (FBF). This paper proposes a noble base-detail separation and detail compensation technique using the contrast sensitivity function (CSF) in the segmented frequency domain. Experimental results show that the proposed rendering method has better sharpness features than previous methods correlated by the human visual system.
