1. Reading of pictures (below left) I=imread(‘Cute Cat.jpg’);%image read, here ” within the ‘path\name’, such as: ‘E:\examples\cute cat.jpg’ figure,imshow(I);%image display title(‘Original image’) 2. Convert to grayscale image (top right) I_gray=rgb2gray(I); figure,imshow(I_gray); title(‘Grayscale image’) One way to see if it is a grayscale image: disp(‘Output string’) % Outputs the string; ndims()% output matrix dimension, here […]
