The All in the Family story makes one wonder how many other gems never had the chance to become classics. The good news, however, is that there are plenty of shows that have stood the test of time. With the help of Wikipedia, and a little math, I found a list of the 20 longest-running network TV shows.
Convolution with a Gaussian kernel (filter) guarantees a non-negative result, so such function maps non-negative values to other non-negative values (f:R+âR+). The result is therefore always another valid image. In general, frequency rejection in Image processing in not as crucial as in 1D signals.
Filtering. 1  Flute filter paper if necessary. Fluting is desirable when a rapid filtration is necessary, as in the filtration of the hot solution during a recrystallization. 2  Place filter paper in the funnel. Place the funnel either directly on top of the beaker or on a ring stand above the beaker (see Figure 1 below).
