MATLAB: Help me plz

image processing

Hi, I want to display all i did for the image (translation, scale, and rotation) but error is still appearing. Can any body help me :'(

this is the code i did:

I=imread('cameraman.jpg');

deg = -30;

I2 = imrotate(I, deg, 'bilinear', 'crop');

J=imresize(I,[900 900],'nearest');

T = [1 0 0; 0 1 0;70 70 1];

tform_translate = maketform('affine', T);

[I3,xdata,ydata] = imtransform(I,tform_translate);

all=I3+I2+J;

imshow(all)

You cannot resize the image and then add it to versions which are not resized.

Matrix addition is only defined for matrices of the same size.

I'm assuming that is your error since you do not give us the error you are getting.
