It can be the highest spatial frequency where a line pattern is visible: See the series on Image sharpness and MTF. It often refers to the total pixel count of an image, e.g., 3072x2048 pixels for the EOS-10D. I prefer either of these definitions to the dpi/ppi setting, which has...
The quality of modern electron microscopes, such as SEM, STEM, and TEM, has greatly improved. However, the quality of the experimental images produced by these instruments is often compromised by stochastic and deterministic distortions arising from the instrument or its environment1,2,3. These dis...
Furthermore, we found that the general shape of MTFr can be expressed parametrically as: MTFr ¼ aeÀ2gb22 þ ð1 À aÞeÀ2gc22 ; (29) where a, b and c are positive real numbers. These numbers were randomly generated until they fulfilled the constraint that on a numerical...

Customers creating SQL on Linux VM's can skip the step of manually installing, running commands, and configuring a SQL Server instance, instead provision a ready-to-go virtual machine running SQL Server. This benefits a lot of customers who might not be interested, or ...
and real strain, with a constant outward shift of about 5%. He also demonstrated that the true positions of atomic columns at the surface could be determined within 0.2 Å, corresponding to 5% of the lattice parameter of gold. This investigation was done before the invention of the spherical...
FIG. 17 shows the effect of myopic blur on image resolution of the peripheral retinal image formed by the reflective optic, as measured by change of the magnitude of MTF at a single spatial frequency (20/200 or 10 line pair per mm “lp/mm” or 10 arc min) as a function of the magn...

much overhead creating separate channel files and saving them before you are allowed to operate on each channel, but so be it. AUTOSTRETCH -linked gives a preliminary stretch which presumably will give a similar result with a variety of images, then a fine tuning MTF darkens the background....
