Question

Write a computer program capable of reducing the number of intensity levels in an image from 256 to 2, in integer powers of 2. The desired number of intensity levels needs to be a variable input to your program

Answer 1

Answer:

Program for Reduction of Gray Level as below:

function img = reductionGrayLevel(image, level)

imageSize = size(image);

num = 256 / level;

 

img = uint8(zeros(imageSize(1), imageSize(2)));

 

for r = 1:1:imageSize(1)

 for c = 1:1:imageSize(2)

  img(r, c) = fix(double(image(r, c)) / num) * 255 / (level-1);

 end

end

end
