Please help! blending of two images!Error: Matrix dimensions must agree

This is my code to blend two images in MATLAB but I am getting an error which says the matrix dimensions must agree in the 12th line , formula for c. Please help

alpha=1;

a = imread('cameraman.bmp');

dimension = size(a);

figure

imshow(a);

title('Original image of Cameraman');

b = imread('lena512.bmp');

dimension = size(b);

figure

imshow(b);

title('Original image of lena');

c=((1-alpha)*a)+(alpha*b);

What are size(a) and size(b) ?

[Aishwarya Bangalore Kumar]

it returns the size of matrices a and b, in this case its an image which produces it

[Walter Roberson]

What are the precise numbers that it shows?

Add following statement Convert the image b to image a size

b1=imresize(b,[rows colm]); 
% Here rows and colm of size of image a

i had changed it to 0.5, but it had the same error

[KALYAN ACHARJYA]

b=imresize(b,[512 512]); % Add

[KALYAN ACHARJYA]

I have run your code no error, add above mentioned line (b=imresize(b,[512 512]);) before c statement

[KALYAN ACHARJYA]

IS it OK?

[Aishwarya Bangalore Kumar]

There is no error, but the output is not blended, is this the code to blend 2 images?
