Explanation:

image degradation function helps 2 understand how a digital image has degraded n how 2 restore it

to come up w the function, start by observing the degraded image. look 4 areas w less degradation n use them as reference of the original

if equipment used 2 take the degraded image is available, try finding the exact conditions which produce the same degradation. dat will provide clues for restoration

if the degraded image can be scanned, it can be manipulated digitally w various pre-programmed functions n look 4 any improvement

one of the above should help in restoring the degraded image

Answer:

Explanation:

In digital image processing, degradation is a process of introducing defects to the image. Understanding the degradation function will allow restoration of the original image.

There are many different causes for image degradation such as motion blur, digital noise and lens off-focus. In cases like motion blur, it is possible to come up with an very good estimate of the actual blurring function and "undo" the blur to restore the original image. For digital noise, a statistical model can be set up to compensate for the degradation it caused. Similarly lens focus can be compensate by an optical model if the mis-focus is known.

The above are three degradations that I could find. A lot more information can be found about restoration functions. If you search for image degradation online, you will find a discussion on Quora and an interesting introduction from Rice University. Good luck!

A broadcast network is one in which a transmission from any one attached station is received by all other attached stations over

love history [14]

Answer:

In a broadcast network such as radio network for example a walkie talkie, the broadcasted transmission is received equally by all receivers indiscriminately which may lead to dissemination of classified information to an unauthorized receiver, therefore, the network layer is required is needed to ensure proper routing of the information

Similarly, when the all the broadcasters in one location are each trying to send messages to different receivers at another given location, there would be potential for network congestion and it would be difficult to send information through the network

When there is need for priority service the presence of a network layer is needed in the network

However, when the above functions performed by the network layer is not required, then, the network layer can be excluded, such as the communication between layers 4 - 7 of the OSI model

Answer:

Clicking the F4 button

Explanation:

The function keys or F keys are in most cases lined along the top of the keyboard and labeled F1 through F12. These keys act as shortcuts, performing certain functions.

The F4 button is a quick way to repeat the last command /action carried out.

For Jessica to continue applying this same style to additional headers, all she needs to do is click the Function Button F4 at the new location where she wants to apply Heading 1 Quick Style.

Other functions of the F4 button are:

Alt+F4 closes the program window currently active in Microsoft Windows.
Ctrl+F4 closes the open window or tab in the active window in Microsoft Windows.
