If an image has only 4 colors, how many bits are necessary to represent one pixel’s color? Describe a new custom encoding that u

ses fewer bits to represent each color in the image. What is your encoding for each color? If you were to re-encode this image using your new encoding, how many bits would you save when compared to the 24 bit RGB encoding?

Answer:

1) 2 bits 2) shown in explanation 3) shown in explanation 4) 22 bits per pixel (2.75 bytes)

Explanation:

As a bit is one of two states, 1 or 0, 2 bits is sufficient to represent 4 colors:

00 = color 1

01 = color 2,

10 = color 3,

11 = color 4

This would be the custom type of encoding for that specific image as it only uses 4 colors.

Now to calculate the amount of memory saved, which is quite simple:

24-2=22

So you Would save 22 bits per pixel or 2.75 bytes per pixel.

Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255
Effectus [21]

Answer:

<em>The programming language is not stated; However, I'll answer the question using C++ programming language, </em>

<em>This program uses comments for explanations  </em>

<em>Program starts here</em>

#include<iostream>

using namespace std;

int main()

{

//Declare Array

int colorcode[3],graycode[3];

//Prompt user for color code

cout<<"Enter Color Code (One on a line)"<<endl<<"Inout Range is 0 to 255"<<endl;

for(int i = 0;i<3;i++)

{

 ccode:  

 cout<<"Enter Color Code "<<i+1<<": ";

 cin>>colorcode[i];

 if(colorcode[i]<0 || colorcode[i]>255)

 {

  cout<<"Input Range is 0 to 255"<<'\n';

  goto ccode;

 }

}

//Initialize smallest to colorcode[0]

int smallest = colorcode[0];

//Determine smallest

for(int i = 0;i<3;i++)

{

 if(colorcode[i]<smallest)

 {

  smallest = colorcode[i];

 }

}

//Determine Graycode

for(int i = 0;i<3;i++)

{

 graycode[i] = colorcode[i] - smallest;

}

//Display Result:

cout<<"Color Code: "<<"(";

for(int i = 0;i<3;i++)

{

 if(i!=2)

 {

 cout<<colorcode[i]<<",";  

 }

 else

 {

  cout<<colorcode[i]<<")"<<endl;  

 }  

}

cout<<"Gray Code: "<<"(";

for(int i = 0;i<3;i++)

{

 if(i!=2)

 {

 cout<<graycode[i]<<",";  

 }

 else

 {

  cout<<graycode[i]<<")"<<endl;  

 }  

}

return 0;

}

The general case in a recursive function is the case for which the solution is obtained directly.
Reika [66]

Answer: False.

Explanation:

The general case of recursive function is when the solution is obtained recursively by simplification at each step.

However, it is the base case in a recursive function when the solution is obtained directly.

The general case must be reducible to base to arrive at a solution else the recursion would be a infinite recursion.
