This error is happening because of the variable input_file has wrong spelling of filename you want to open, or the file is not placed in the current directory. Use it like this

 input_file = 'myFile.txt'; % specify full fine name, along with extension.
 image_files    = textread(input_file,'%s');

Also, make sure the file named 'myFile.txt' is present in the current directory.

I found this code in github : https://github.com/suyogduttjain/fusionseg

And I try To execute This code now :

%1 = appearance model
%2 = motion model
model_type = 1; 

if model_type == 1
  data_dir = './images/';
  input_file = './appearance_image_list.txt';
  output_file = './appearance_output_list.txt';
elseif model_type == 2
  data_dir = './motion_images/';
  input_file = './motion_image_list.txt';
  output_file = './motion_output_list.txt';
else
  return;
end
image_files    = textread(input_file,'%s');
image_prefixes = textread(output_file,'%s');
num_images = length(image_files);

for i = 1:num_images
  feature_name = [image_prefixes{i} '_blob_0.mat'];
  data = load(fullfile(data_dir, feature_name));
  raw_result = data.data;
  
  img = imread(fullfile(data_dir,image_files{i}));
  img_row = min(size(img, 1),size(raw_result,1));
  img_col = min(size(img, 2),size(raw_result,2));
  raw_result = permute(raw_result, [2 1 3]);
  
  probs = raw_result(1:img_row, 1:img_col, :);
  [~, mask] = max(probs,[],3);
  mask = logical(mask-1);
  
  figure(1);
  subplot(2,2,1);
  imshow(img);
  
  subplot(2,2,2);
  imshow(mask);
  title('Object Mask');
  
  subplot(2,2,3);
  imagesc(probs(:,:,2));
  axis image;
  title('Object Probability');
  
  pause;

end

is appearance_image_list.txt present in your working directory?
