main.m
% Read input images
img1 = imread('image1.jpg');
img2 = imread('image2.jpg');

% Convert images to grayscale
img1_gray = rgb2gray(img1);
img2_gray = rgb2gray(img2);

% Normalize the pixel values
img1_norm = double(img1_gray)/255;
img2_norm = double(img2_gray)/255;

% Perform convolution and scale the output image
C = conv2(img1_norm, img2_norm);
C = mat2gray(C);

% Display input and output images
figure;
subplot(2,2,1); imshow(img1_gray); title('Input image 1');
subplot(2,2,2); imshow(img2_gray); title('Input image 2');
subplot(2,2,[3,4]); imshow(C); title('Convolution of two images');
