I have a folder that contain about 120 face images with their coordinates in txt formats. I need a matlab code that can read or import each of the coordinates and plot it on a face images. E.g, read or import coordinates for image 1 and plot it on image 1, then read or import coordinates for images 2 and plot it on image 2 and so on till the end. I can do it for individual images but i want a code that can do all at once simultaneously (read/import and plot, read/import and plot). Please help. An example of the coordinates in txt format is shown below. To see the data better, i have uploaded the a sample of the data file in txt format. (1-1.txt)

There is no chance to reconstruct a "face" based on the example data you gave us. The meaning of the values has not been defined. Are these points?
What have you tried so far?

Yes, these are points. I have tried reading multiples face images at once, which works. I have tried importing data from a file and plotting it on a face, which also works. What i want now is to read/import all the data and be plotting on the face individually simultaneously. A code that will read all the images with the points plotted on them. I have also attach upload the a sample of the data in .txt format.

If I understand correctly, you want to process multiple text files which contain X,Y coordinates. Try:
files = dir('*.txt');
nfiles = numel(files);
yourdata = cell(1,nfiles);
for i=1:nfiles
fileID = fopen(files(i).name);
yourdata{1,i} = textscan(fileID,'%f%f','HeaderLines',1);
fclose(fileID);
end
yourdata is a cell array, where every cell contains X and Y data from each .txt file. You may then use the data for plotting.
for i=1:nfiles
figure
plot(yourdata{i}{1}, yourdata{i}{2});
end
