I have this question :

1-Read an image.

2-Show that image.

3-Write the image to the disk by new name.

4-What is the intensity value of the pixel located at position(4,7)?

*I solved the previous four questions, but Is the Solution is correct ?

figure

image_mat = imread('Picture3.jpg'); % image_mat is simply a matrix

imshow(image_mat);

imwrite(image_mat,'House.jpg');

disp(image_mat(4, 7))

imshow(image_mat);
