create am encoder in matlab

To create an encoder in MATLAB, you first need to define the encoding logic that you want to implement. Here is a simple example of an encoder that increments the pixel values of an image by a certain factor:

main.m
% Read the input image
input_img = imread('input_image.jpg');

% Define the encoding factor (you can change this value as needed)
encoding_factor = 2;

% Add the encoding logic (increment pixel values by encoding factor)
encoded_img = input_img + encoding_factor;

% Display the original and encoded images
figure;
subplot(1, 2, 1);
imshow(input_img);
title('Original Image');

subplot(1, 2, 2);
imshow(encoded_img);
title('Encoded Image');

% Save the encoded image
imwrite(encoded_img, 'encoded_image.jpg');
510 chars
22 lines

In this example, we first read an input image, define an encoding factor, apply the encoding logic by incrementing the pixel values of the input image, display the original and encoded images side by side, and save the encoded image to a file.

You can customize and expand this basic encoding logic based on your specific requirements.
