I have face images along with their .pts file. I want to read face image one by one along with its .pts file.
I tried it. I am not getting any error in this code.
I just want to do this task using one for loop. So, I can read one face image along with its own .pts file (not all .pts files ) because if i will use two for loops in that case outside for loop will read first one image after that second for loop will read all .pts files,but i donot want this thing.
if true
% code
srcFiles = dir('E:\imagetest\*.jpg'); % the folder in which ur images exists
for j = 1 : length(srcFiles)
filename = strcat('E:\imagetest\',srcFiles(j).name);
I = imread(filename);
Filelist=dir('E:\TEST')% the folder in which .pts file exist
counter = 1;
FSize = size(Filelist);
for i=3:4%numel(Filelist)
filename = strcat('E:\TEST\',Filelist(i).name);
[FileId errmsg]=fopen(filename)
npoints=textscan(FileId,'%s %f',1,'HeaderLines',1);
points=textscan(FileId,'%f %f',npoints{2},'MultipleDelimsAsOne',2,'Headerlines',2)
Y=cell2mat(points);
end
end
end
%%Example of .pts file
version: 1
n_points: 4
{
115.947 221.239
121.382 250.566
130.001 279.096
141.677 306.538
}

imgdir = 'E:\imagetest';
ptsdir = 'E:\TEST';
jpegwild = fullfile(imgdir, '*.jpg');
srcFiles = dir(jpegwild); % the folder in which ur images exists
for j = 1 : length(srcFiles)
imgfilename = srcFiles(j).name;
fullimgfilename = fullfile(imgdir,imgfilename);
[filepath, basename, ext] = fileparts(imgfilename);
fullptsfilename = fullfile(testdir, [basename '.pts']);
if ~exist(fullptsfilename,'file')
fprintf(2, 'Image "%s" did not have a corresponding .pts file\n", imgfilename);
continue;
end
I{j} = imread(fullimgfilename);
[FileId, errmsg] = fopen(fullptsfilename);
npoints = textscan(FileId,'%s %f',1,'HeaderLines',1);
points = textscan(FileId,'%f %f', npoints{2}, 'MultipleDelimsAsOne', 2, 'Headerlines', 2, 'CollectOutput, 1);
fclose(FileId);
Y{j} = points{1};
end
This forms the cell arrays I{k} being the k'th image and Y{k} being the corresponding points
