Write a MATLAB program for Image Negation

Code:

clear;

clc;

a = imread('d:/matimage/baby.jpg'); % Read image from graphics file

b = 255-a; % conversion from black to white and vice-versa (black =0 and white = 255)

subplot(2,1,1), %Create axes in tiled positions

imshow(a), % displays the original image.

title('original image'); % Add title to current axes

subplot(2,1,2), %Create axes in tiled positions.

imshow(b), % displays the negative of original image.

title('negative of original image'); % Add title to current axes

Output:
