Figure 6From: A framework for measuring sharpness in natural images captured by digital cameras based on reference image and local areasSubjective sharpness values for Datasets I and II. The subjective sharpness values on the vertical axis (scale, 0-100), with 95% confidence intervals are sorted in ascending order (on the horizontal axis), for Datasets I (with 13 cameras) and II (with 14 cameras).Back to article page
