HVS의 CSF 특성을 고려한 HDR 영상의 선예도 개선

다국어 초록 (Multilingual Abstract)

iCAM06, the representative algorithm among the various HDR rendering techniques, uses fast-bilateral filter for its fast computation time. Because fast-bilateral filter uses piecewise-linear approximation and down-sampling concept in processing of image decomposition for color adaptation and tone compression, iCAM06 has a tendency to reduce the sharpness of HDR image. To solve this problem, we propose a sharpness compensation filter using contrast sensitivity function (CSF) for the sharpness enhancement of HDR images considering HVS(human vision system) in iCAM06. Experimental results show that the iCAM06 rendering using the proposed filter has better sharpness performance than default iCAM06 in the subjective and objective performance evaluation.
