want to read all images in specific folder But the error occur and I don't know why and what to do. i need help

code :

clear all;

close all;

disp(' ')

disp('Step 1:')

filter_bank = construct_Gabor_filters_PhD(8, 5, [180 160]);

data_matrix = [];

ids = [];

conut = 0;

% construct image string, load image and extract features

for i=1:503

for j=1:5

s = sprintf('D:\ajorMinorKnuckleFingerprint\First Minor knuckle index\%i_%i.bmp',i,j);

X = imread(s);

X=rgb2gray(X);

featureg= filter_image_with_Gabor_bank_PhD(X,filter_bank,64);

data_matrix = [data_matrix,bsifhistr(:)];

bsifhistr=bsif(X,ICAtextureFilters,'nh');

data_matrix=[data_matrix,bsifhistr(:)];

ids = [ids;i];

conut = conut+1;

disp(sprintf('Finished with feature extraction from image %i/%i',conut,400));

end

end

and this is erreur :

It looks like the problem is this line:

s = sprintf('D:\ajorMinorKnuckleFingerprint\First Minor knuckle index\%i_%i.bmp',i,j);

It would help if you can

1. describe in words what you were trying to accomplish with that line, and
2. provide an unambiguous example filename (perhaps for i=1 and j=2) that you would like the sprintf line to create.

The backslash has special meaning in MATLAB as an escape character. If you actually want a backslash, you have to use "\\".

i=1;
j=3;
s = sprintf('D:\\ajorMinorKnuckleFingerprint\\First Minor knuckle index\\%i_%i.bmp',i,j)

s = 'D:\ajorMinorKnuckleFingerprint\First Minor knuckle index\1_3.bmp'
