b. Terminating in an edge or a point: sharp angular cliffs; a sharp nose. c. Clearly and distinctly set forth: sharp contrasts in behavior. 3. Abrupt or acute: a sharp drop; a sharp turn. 4. a. Intellectually penetrating; astute: was sharp in his analysis of the problem. b. Marke...
The perceived sharpness of a print or display is measured by Subjective Quality Factor (SQF) or Acutance, which are derived from MTF, the Contrast Sensitivity Function of the human eye, and viewing conditions. Imatest‘s primary sharpness measurement uses slanted-edge patterns analyzed by SFRplus,...
In sharp contrast, Latin American countries have witnessed a decline in infrastructural investment since the 1980s as a result of increased fiscal austerity. 与此形成鲜明对照的是,由于财政紧缩加剧,拉丁美洲国家在基础设施方面的投资自1980年代以来有减无增。 UN-2 The subvention of the health sector...
Use a variety of tools, filters, and masks, such as Smart Sharpen, to adjust image sharpness and blur in Adobe Photoshop. You can also use the Unsharp mask, which sharpens a photo by increasing contrast along the photo's edges.

Takeaway—Almost any image of a slanted-edge will work as long as it’s displayed with the maximum sharpness of the monitor. 10:1 contrast is recommended. 2. Capture a high-resolution image of your display Camera and lens—Use a high quality mirrorless or industrial camera to photograph your...
This method differs quite significantly from ours in that it does not assume an underlying sharpness condition (1.9) (although such a condition is used in the analysis to obtain explicit complexity bounds). In contrast to [67], our method is independent of the total number of iterations, and...
a key process for maintaining the tropopause sharpness in idealized simulations is the inclusion of a thermal relaxation toward a state with a smooth equator-to-pole PV gradient, as an idealized representation of other diabatic processes, which acts to maintain the contrast between the high-PV str...
