reading a single image on matlab

   [filename,pathname]=uigetfile('*.jpg','Select the image');
   B= imread(fullfile(pathname,filename), 'jpg'); 
   figure(1);
   imshow(B);
    
---------------------------------------------------------------------------------------------------
            
   B = imread(sprintf('/Users/aylin/Desktop/plants ', k)); // my mistake is in here. how can i solve it? (on macOS)
   B = imresize(B,[1000,260]);
   [I3,RGB] = createMask(B);
   seg_img = RGB;
   img = rgb2gray(seg_img);
   glcms = graycomatrix(img);

---------------------------------------------------------------------------------------------------

so which version i should use? i am trying to read images from a folder. i select one of the images and then my codes are analysing them.This parts giving error..

aylin - from your line of code

B = imread(sprintf('/Users/aylin/Desktop/plants ', k)); // my mistake is in here. how can i solve it? (on macOS

what is k? Where is the extension for the file that you want to read? Are all of your file names witten as 1.jpg, 2.jpg, etc.? Is plants a folder or a file name? Please clarify.

[aylin yilmaz]

k is coming from :

xx = 1;

for k=1:20.

and yes my file names written as .jpg, 2.jpg, etc.

plants is a folder which contains jpg files.

---------------------------------------------------------------------

and here the extension for the files:

if (choice==2)

[filename, pathname] = uigetfile({'*.*';'*.bmp';'*.jpg';'*.gif'}, 'Pick a Leaf Image File');

I = imread([pathname,filename]);

I = imresize(I,[1000,260]);

figure, imshow(I); title('Query Leaf Image');

imread(fullfile(pathname, filename)) is better code. You cannot be sure that uigetfile() will return a directory separator at the end of pathname.

[Walter Roberson]

projectdir = '/Users/aylin/Desktop/plants';

thisfile = fullfile(projectdir, sprintf('%d.jpg', k));
B = imread( thisfile );

** i changed the folder name as Final File.

[Walter Roberson]

Where did the () come from? I did not put any () in '%d.jpg' ?

[aylin yilmaz]

my file names are written as (1).jpg, (2).jpg etc..

[Walter Roberson]

If you use

! ls '/Users/aylin/Desktop/Final File/'

then does (1).jpg show up there? What shows up for

! find '/Users/aylin/Desktop' -name '(1).jpg' -print

Note that those ! are part of the command.

[aylin yilmaz]

in the folder, i do see a file name written as (1).jpg..

it shows nothing actually, it's just showing errors..

[Walter Roberson]

Please run this and show us the output.

projectdir = '/Users/aylin/Desktop/Final File/';
try
  olddir = cd(projectdir);
catch ME
    error('Could not cd to "%s"', projectdir);
end
dinfo = dir('*.jpg');
if isempty(dinfo)
    fprintf('No .jpg files in directory "%s"', projectdir);
else
    for K = 1 : length(dinfo)
        thisfile = dinfo(K).name;
        fprintf('Found .jpg file "%s"\nThe character positions for the filename are:\n', thisfile);
        disp(thisfile+0);
    end
end
dinfo = dir('(*.*');
if isempty(dinfo)
    fprintf('No files beginning with "(" in directory "%s"', projectdir);
else
    for K = 1 : length(dinfo)
        thisfile = dinfo(K).name;
        fprintf('Found "(" file "%s"\nThe character positions for the filename are:\n', thisfile);
        disp(thisfile+0);
    end
end
