texture. Proper photographic and post-processing technique can go a long way towards improving sharpness, although sharpness is ultimately limited by your camera equipment, image magnification and viewing distance. Two fundamental factors contribute to the perceived sharpness of an image: resolution and ...

visual contrast sensitivity function (CSF) and of device spatial resolution, characterized via the modulation transfer function (MTF), can be used to determine the optimum correction to be made to the sharpness of an image for specified viewing conditions, via parametric image processing techniques. ...
Image sharpness can be measured by the “rise distance” of an edge within the image. With this technique, sharpness can be determined by the distance of a pixel level between 10% to 90% of its final value (also called 10-90% rise distance; see Figure 3). Figure 3. Illustration of...
PURPOSE: To evaluate the sharpness of an image through easy arithmetic operation by finding a density difference histogram and a cumulative division histogram and determining the relative sharpness between two images according to a cumulation rate up to a specific density difference. ;CONSTITUTION: Plura...
