Reading and processing Images

Hello I have images saved in a mat file and I'm trying to read and extract feautures from the images. I need help please. Here is my codes reading the txt file

fid = fopen('file.txt');
for i = 1: 100
x = textscan(fid,'%s\n');
fn{i,1};
fn{i,1} = x{1,1};
end
 save filenames fn

% My code to read the image I need help with 
for i = 1:100
I = imread([fn{i,1}]);

Hey Chidiebere,

The question is not very clear. Can you please explain

1. The purpose of reading the text file?
2. Where you want to fit the "code to read the image" ?
3. What error you are getting?
4. Your overall aim for the code

Hello thanks for having a look I deciced to do it differently I'm getting this error :

Error using imread>get _full_ filename(line 565)

Cannot open file 'C :\users\chidiebere \onedrive\documents\project'' . for reading.You might not have read permission.

Error in Imread (line 337)

fullname=get_full_filename(filename);

Here is my code

file_list = dir('C:\Users\Chidiebere\OneDrive\Documents\PROJECT');

nfiles = length(file_list);

mydataGLCM = [];

for k = 1 : nfiles

I = imread(strcat('C:\Users\Chidiebere\OneDrive\Documents\PROJECT',file_list(k).name));

end

GLCM_values = graycomatrix(I);

stats = graycoprops(GLCM_values{'contrast','homogeneity','Correlation','Energy'});

Contrast = stats.Contrast;

Correlation = stats.Correlation;

Energy = stats.Energy;

Homogeneity = stats.Homogeneity;

feat = [Contrast,Correlation,Energy,Homogeneity];

mydataGLCM = [mydataGLCM, feat(:)];

if k == 1

save('newMethod.mat','mydataGLCM');

else

save('newMethod.mat','mydataGLCM','-append');

end

end

Well, first read the error-message. Then check if it is giving you information of value. In this case:

1. Does the directory "C :\users\chidiebere \onedrive\documents\project" exist? (Should there be a white-space between the C and the :?, between chidiebere and \onedrive?)
2. Do you have read-permissions in that directory?

Once youve checked that then you can proceed with further questions.
