1. Briefly explain the concept of signature of a function, in a function declaration. What signature components are crucial for

Irina18 [472]

Answer:

Function signature can be defined as a combined term used to refer to the function name, function return type, no of arguments , type of arguments.

Explanation:

The signature of function is seen as a combined term used to refer to the function name, function return type, number of arguments , type of arguments.

When overloaded functions is been defined, they are different in numbet of arguments or type of argument passed.

To understand this better refer to the program code below.

C++ code.

#include <iostream>

using namespace std;

int multiply(int a, int b)

{

cout << a*b <<endl;

return 0;

}

int multiply(int a, int b, int c)

{

cout << a*b*c <<endl;

return 0;

}

int main()

{

//function with two arguments passed

multiply(3, 50);

//function with three arguments passed . It is different in number of arguments passed. Thus here function signature is different

multiply(4, 20, 10);

}

100 POINTS. DO NOT SPAM. OR I WILL REPORT.

Dafna1 [17]

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!
