create cnn autoencoder for delete from pictures watermarks in matlab

main.m
% Load the input image
inputImage = imread('watermarkedImage.jpg');

% Define the autoencoder architecture
hiddenSize = 500;
autoencoder = trainAutoencoder(inputImage, hiddenSize, 'MaxEpochs', 100);

% Encode the input image
encodedImage = encode(autoencoder, inputImage);

% Remove the watermark by setting the lowest encoded pixel values to zero
encodedImage(encodedImage<0.1) = 0;

% Decode the encoded image
decodedImage = decode(autoencoder, encodedImage);

% Show the input, encoded and decoded images side by side
montage({inputImage, encodedImage, decodedImage});

% Save the decoded image as output
imwrite(decodedImage, 'removedWatermark.jpg');
