I have an image database as files (106 files and each file contains 48 images)
I want to generate a matrix for the database (db.mat)
I want my program to open each folder (from 001 to 106) and take the data and save it to a db.mat file
here is my prog :
clear all;
clc;
cd D:\001\FT-2BU\FT-2BU
s = '';
str1 ='00';
str2 ='0';
for i=1:106
if i<10
s=strcat(str1,i);
bmpFiles = dir('*.bmp');
numfiles = length(bmpFiles);
mydata = cell(1, numfiles);
for k = 1:numfiles
mydata{k} = imread(bmpFiles(k).name);
end
save mydata;
elseif i<100
s=strcat(str2,i);
bmpFiles = dir('*.bmp');
numfiles = length(bmpFiles);
mydata = cell(1, numfiles);
for k = 1:numfiles
mydata{k} = imread(bmpFiles(k).name);
end
save mydata;
else
s=i;
bmpFiles = dir('*.bmp');
numfiles = length(bmpFiles);
mydata = cell(1, numfiles);
for k = 1:numfiles
mydata{k} = imread(bmpFiles(k).name);
end
save mydata; end
end
end

dir(fullfile(folder,subfolder))
