Three-D (3-D) stereo video is becoming widely available and one need to consider depth effects when extending the 2-D video processing algorithms to 3-D stereo set-up. Depth is the additional attribute which contributes to overall visual quality of the 3-D stereo video. Sharpness enhancement algorithm is commonly applied in 2-D video processing chain; the effect of depth perception when sharpness enhancement algorithm is applied to the 3-D stereo video is studied. A subjective experiment is presented to study the relation between blur/sharpness and depth. A concept of just noticeable blur (JNB) at different depths is introduced for the stereo image pairs. Based on the results of the experiment an adaptive sharpness enhancement algorithm is proposed. The visual quality results, of the proposed depth aware sharpness enhancement algorithm, are presented.
