create auto encoder for deleting object from pictures in matlab

To create an autoencoder for deleting objects from pictures in MATLAB, you can follow these steps:

  1. Load the image and the object you want to delete from the image.
main.m
img = imread('image.png');
obj = imread('object.png');

  1. Convert the images to grayscale if they are not already grayscale.
main.m
img = rgb2gray(img);
obj = rgb2gray(obj);

3 lines
  1. Normalize the pixel values of the images to be between 0 and 1.
main.m
img = im2double(img);
obj = im2double(obj);

  1. Create the training data for the autoencoder by removing the object from the image.
main.m
trainingData = img - obj;

26 chars
2 lines
  1. Specify the layers of the autoencoder.
main.m
inputSize = size(trainingData,1)*size(trainingData,2);
hiddenSize = 100;
autoenc = trainAutoencoder(trainingData(:,:), hiddenSize, 'MaxEpochs', 200);

  1. Test the autoencoder on a new image.
main.m
newImg = imread('newimage.png');
newImg = im2double(rgb2gray(newImg));
reconstructedImg = predict(autoenc, newImg(:,:));

  1. Display the reconstructed image.
main.m
imshow(newImg);
title('Original Image');
figure;
imshow(reconstructedImg);
title('Reconstructed Image with Object Deleted');

This autoencoder will learn to remove the object from the image by reconstructing the input image using the training data.
